History and basic information about printers and MFP

If you are asked to call peripheral device For a computer, with the most likely the printer will come first to mind. Devices with similar functionality appeared long before the monitors, that is, computers could not show anything, but could already print the information. Name the first devices with full printers are quite difficult, because during computers the size of the compactness of the output devices is unlikely to think.

Everything has changed with the appearance personal computers. Printers following computers also began to decrease in size, gradually reaching a modern level. There were several technologies for which printers worked, their functionality expanded. One of the most common printing technologies has become, and so far is the so-called laser printing. In the pluses of laser printers, you can record low print cost, although not the lowest: Matrix printers are printed significantly cheaper, but at the same time very slow and noisy. Other advantages of printers performed on this technology is high performance, reliability and simplicity in service. The high price for such devices for a long time did not allow them to use them at home, but a few years ago the situation has changed, and now laser printers Steel are available - not only monochrome, but also colored.

In addition, over the past few years, a new class of devices that combine the functions of the printer, scanner have been formed copyrocaust And even fax. Such combined solutions are called multifunctional devices, or MFP. Let's try to choose a printer or MFP, most appropriate for specific tasks.

As you know, the image on the monitor is output as points. The number of these points vertically and the horizontal is called the resolution and it looks usually as 1920x1080. Agree that the printer resolution is usually denoted as 1200dpi or 1200 x 1200 DPI, it is difficult to relate to the image resolution, however, despite the different writing, it is essentially the same. The mysterious combination of "DPI" letters means "DOTS PER INCH" (dots per inch), that is, the number of points that the printer can print on one inches (2.54 cm). This parameter is key, because It is according to it that you can determine the quality of the finished print. The higher the resolution, the better the finished print. Sometimes the resolution of printers is indicated as 2400 x 600 DPI. This means that the horizontal resolution differs from the resolution by vertical, that is, each point printed by the printer has no square, but a rectangular shape. High resolution will be especially useful if necessary. large volumes Text small font or a large number of images.

If you need a printer exclusively for printing text, then anyone with a resolution of 600 dpi is suitable, and more resolution will rather be a disadvantage, since when printing at higher resolution, toner consumption increases. If you plan to print graphs, small text, such as crib, then a high resolution It will be a very important parameter.

Printer print resolution and, no matter how strange it seems, the amount of its memory is closely related parameters, which largely depends the productivity of the printer.
In the description of the printers, the amount of memory is always specified, for example, for samsung Models SCX-3205 It is 32 MB. The more this parameter, the more high-quality images can print the printer. For example, it will take 3.75 MB to print a picture of 1280x1024, and for the image 2560x2048 - already 15 MB.

The more high-quality images are planned to be printed, the more memory you need a printer. It should be borne in mind that all documents are transmitted to the printer as images. Also, the large amount of memory will be useful if access to the printer is carried out by several users, for example, when connected via a local network. Everything is simple here: the more memory, the more print jobs can be sent and the faster they will be fulfilled.

A device that combines the scanner and printer functions has a number of advantages over the scanner and printer used separately. First, such a technical solution takes less space on the table. Indeed, the scanner installed on the printer takes less space than two devices installed nearby.

The second, no less important, the advantage is the possibility of offline copying. You do not have to turn on the computer if you need to make a copy of any document (such situations with different periodicity are each). Autonomy is the lack of need to include a computer and run specialized programs. Thus, you simply place the original in the scanner, select the number of copies using the device control keys and click "Copy".

Quite often, you need to print a document from two sides of the sheet. The easiest way is to print a sheet on one side, flip over and print with arc. It would seem that nothing complicated. And now imagine that there are 124 such sheets. Agree, not very interesting pastime.

To facilitate this procedure, printers with support for double-sided printing were developed, or, as they are more often called, printers with Duplex Unit. Such printers independently turn each sheet after one of the sides is printed. An example of a device with Duplex Unit can serve as Samsung SCX-4728FD MFP, designed for office applications.

Scanning is a process, reverse printing, that is, enter the image from the paper sheet into the computer. The more points can recognize the scanner, the more accurate the image on the screen will look. Thus, the quality of the scanned image affects the resolution of the scanner. As in print, the scan resolution is measured at inch points (DPI), and the higher it is higher, the better the finished picture.

Resolution without additional processing With the help of software is called optical, and it is precisely to pay attention to it when choosing a MFP. For example, the SAMSUNG CLX-3185FN MFP scanner has a scanner optical resolution 1200 x 1200 DPI, that is, for every 2.54 cm vertically and horizontally, the scanner will remove 1200 points.

What if you need to scan or copy a large number of pages?
As in the case of bilateral printing, there are two ways here. One way from the Stone Age, that is, you must independently change the leaf behind the leaves. It is inconvenient, and we live in the 21st century, so such a way is not for us.

The second way of facilitating this simple, but the routine task is an automatic document feeder, or ADF. Using this option, scanning a pack of sheets will be more comfortable. Just load the packs of the sheets, click "Scan" and wait for the result. This option boasts many Samsung MFPs, such as Samsung SCX-4623F.

When choosing a printer, you should pay attention to the method of connecting this device to a computer. If you have one computer and further acquisition of a computer or a laptop for family members is not foreseen, in this case there is an absolutely any printer with a USB port, as it is now more difficult to find a computer without this connector. If a printer has several people, it is better to choose a printer with a built-in WiFi adapter or network interface.

The advantage of WiFi is the lack of wires, allowing you to install such a printer at any convenient place - the main thing is to have a socket nearby. An excellent example of such a device is the Samsung ML-1865W - a small printer with an elegant design is perfect for the home, and thanks to the support of WiFi, any family member will be able to use (author's note: you need WiFi router - purchased separately).

The network interface is less convenient: since the wires are required to connect such devices to the network, it is better to use them in places where it is already built the local network And there are free network sockets - for example, in offices.

It's hard to imagine how to do work with a printer more comfortable. It would seem that it is worth the box: I sent a print job, she chained and betrayed the finished imprint. But there is no limit to perfection.

Samsung has tremendous experience in the production of various consumer electronics and knows how to make a device is pleasant from any point of view. Let's look at some branded technologies that will make work with a printer pleasant.

In all Samsung printers implemented technologies to reduce the noise during the device. Agree than the quiet device, the less discomfort it causes - especially at home and especially at night, when every rustle is heard around quietly and heard.

Many Samsung's Printer Models and MFPs have a print button from a screen that will play on paper a copy of the screen contents. This is convenient, for example, if necessary, print electronic tickets or map of the area from the relevant Internet services.

The Samsung AnyWeb Print application greatly facilitates the collection of information: viewing web pages, you can highlight and drag any fragments on the print bar in the browser window. AnyWeb Print will help to compose and process any information you have interested in the network, whether it needs to work on an important project or just for entertainment.

For system administrators It will be very convenient that all Samsung printers work with a single Universal Print Driver driver, which support all Samsung printer models. Maybe for home use This is not as critical, but for an enterprise, where simple equipment costs weekly, such functionality will be very useful.

Finally, I would like to say a few words about environmental protection. Samsung is striving to reduce the negative impact on the environment when working all its devices. Printers and MFPs are no exception. Most of the modern SAMSUNG printing devices is equipped with an innovative button "Eco-Button". When you press this button, the consumption of paper and toner is automatically reduced, allowing you to minimize operating costs and, which is equally important, the factor of the anthropogenic environmental impact.

Many users of printing devices want to know the answer to the question of how to see the print history of the printer. Thanks to this, you can track what file and when was printed on your device. Thus, you can establish a kind of print control, which can be very useful.

Sequencing

So, to get the print history of the printer, you need to enable a special function that is intended to maintain the log of all the files, which are printed on the print server, which can be used both remote and local devices. For this purpose, go to the "Printers and Fax" section, after opening through the "Start" menu, the computer control panel.

• Next, click on the file and open the Server Properties window.
• Click the tab with additional parametersTo mark an item called "Move the message queue messages."
• In order to view which files and when were printed using your device, open the control panel and go to Administrative Section.
• Click in a new window to "View Events", followed by the item called "System".
• Then run the search process by specifying the source of the events that you are interested in "Print". Issued as a result you can sort.

In general, as you can see, it is very simple to see the history of printers. The main thing is to initially include the above-mentioned function.

Using special programs

To solve the task associated with how to find out which documents were printed on the printer, you can download absolutely free software application O & K Print Watch.

It should be immediately noted that this means It is intended not only to keep accurate print statistics, but also distinguish between access controls to printers.

This software has a special printing system on devices, which, if necessary, can be exported to formats such as XML / HTML. To create a report for a specific object, it is enough to start the program and click on the "Report" point, then click on the Start Report command. The final document with the list of printed files, and when they were printed and what particular user can be presented as a common or detailed report. It should be noted that each default report is created from the last thousand records. To change this value, you just go from the "Report" menu to the "Parameters" item and install all the necessary values.

A good solution to learn about what they did on the printer is to use the name called Print Manager Plus. Due to the fact that the program has support for printing devices of all major manufacturers, it can make it possible to track statistics on the job tasks with maximum accuracy. And it can do it not only inside LANs that have several printers, but also in sufficiently large companies with a variety of printing devices models.

The PCounter software application is a comprehensive solution to audit printing processes across a whole enterprise. It allows you to track and keep a collection of statistics on how which file and what device prints. In addition, using this program you can keep records of the total amount of tasks sent to print on the network. It should also be added that the pcounter can easily be integrated into the available infrastructure and scaled further.

In addition to the described programs, with the help of which you can see the history of printing office equipment, there are quite a few others. Setting one of these multifunctional programs will solve some other tasks, for example, to manage print queue, monitor consumables, prohibit printing, etc.

One of the most important technical points The amount of printer's memory is considered, it is often overlooked, but it is permissible in cases of normal use of the printing device. What is meant by usual use? We are talking about default parameters.

For example, the device is designed for small working groups in the office or at home with a small download of documents. Of course, such a printer has an operational reserve. It can easily print a rather large amount of documents and a diploma included. In the case of network work and printing from different departments of the company in the queue, including photo photos, such a device can no longer process tasks.

You will receive a message that the RAM is full with all the ensuing consequences of the service engineer - it is not always possible to restore performance after an error in the network infrastructure with the usual reboot of parameters.

What will we talk about:

Lack of memory - error or malfunction?

IN this case It is not about the fault, but about the memory of the printer. Its volume can be found in the description of the model. Typically, the base volume is set, which is designed for model tasks. For this reason, superfluous load is not recommended. At the same time, there is always the possibility of expansion.

The prompt memory of the printer has the same interface as computers. Therefore, it is enough to purchase an additional slot to the extension and install it on motherboard Printing device. Is it possible to do this yourself, and is it possible to do this on the already acquired device? Sure.

The disadvantage of memory is not a malfunction, we are simply about the use of the printing device is not intended. Typically basic set technical parameters It is enough to perform tasks that are declared by the manufacturer in the description. But not always consumers use recommendations for selecting a model. In this case, there is also a way out of the position, it suffices to contact the service and establish, for example, additional memory of the HP printer.

To speak specifically about this brand, the brand produces high-speed and high-performance models that are designed for a sufficiently large amount of work even in basic functionality. And the upgrade does not need to do, but there are always exceptions. In this case, required right choice Microcircuits and correct installation.

What signs talk about problems in random access memory:

• the printer processes with errors simple tasks to print;
• the device "hangs" and requires a reboot;
• the queue is not processed.

It is worth making a remark. Even the most good device By default, it may fail. In this case, we are talking about logical errors in the installed slot. If there is often a problem with the problem of processing simple tasks, and messages are issued that the memory is filled, we recommend that you test this particular component. It is not excluded that the slot replacement will be required.

"Comfortable" or basic RAM on printers

Modern models have established today specifications. These include the built-in memory with which the recommended model will work without failures. The volume affects the quality of the output of gradients, small objects and other photo elements. With an overpressure of the microcircuit turns out to be filled.

Laser

The basic built-in printer memory has the following values \u200b\u200bin laser and inkjet models, list some facts:

• models of past years have on board 2 MB, with the ability to expand up to 32 MB;
• at the new HP LaserJet Ultra M134A there is a 128 MB base slot (see photo);
• on new HP models, a 144-pin slot256 MB DDR2 DIMM is installed;
• hP LaserJet Pro M227FDN or HP Color LaserJet Pro M274n costs 256 MB.

Thus, modern laser models have 128-256 MB (the basic quantity depends on the series), outdated from 2 MB, depending on the model. Please note that the new print devices are set by DDR, in old models there is a SIMM, so it is not always possible to make a full replacement or expansion. PCI connectors outdated models are simply not designed for new microcircuits.

Jet

The principle of operation of the inkjet device is somewhat different, in many respects resembling a matrix. For image processing, instead of a built-in slot, there is a graphic coprocessor. Image processing is carried out in the cache.

For these purposes, such a concept is used as "virtual memory" using intermediate data when processing the postScript language. Calculations are carried out on the computer where the virtual segment is opened are transmitted along the high-speed interface and in the queue of the cache and are printed sequentially. In a simplified form, the processing occurs in this way, so that these models handle the image on another principle. Using computer power favorably features inkjet technology lower price.

Conclusion

When choosing, pay attention to the manufacturer's recommendations regarding the features of operation. In this case, the characteristics fully meet the task. You can buy a suitable model for your tasks with a basic set of technical capabilities. If it is still mistaken and an error is issued, you can always open the case and install a new built-in slot.

This printer has three slots for installing modules. dimm memorywhich can be used as follows:

Expansion of the printer's memory. Dimm 16.32 and 64 MB (maximum volume 192 MB) are available.

DIMM flash memory modules, each volume 2 and 4 MB. Unlike standard memory Printer, DIMM flash memory can be used to constantly storing loaded components in memory, even when the printer is turned off.

Flash memory can store fonts, macros, EWS or patterns.

Other languages \u200b\u200band printer parameters based on DIMM.

Memory modules with single-row contacts (SIMM) used in previous HP LaserJet printer models are not compatible with this printer.

You may need to install additional memory to the printer if you often print complex graphics or documents in PS languages, print using an optional double-sided print module, use many downloaded fonts, print in ProRes1200 mode or using large paper formats.

The printer has two extended I / O slots to ensure the work of the printer with the following devices:

LAN card.

Storage device for large volumes, for example, hDD.

To determine the amount of memory installed in the printer, or modules installed in the slots, print a configuration page.

Installing Dimm Memory Modules

Static electricity can damage memory modules with double-row contacts (DIMM). When working with DIMM modules, wear an antistatic bracelet or periodically touch the surface of the antistatic packaging and to the open metal part in the printer.

If you have not yet printed a configuration page, print it to determine which amount of memory is already installed in the printer before installing additional memory.

1 Turn off the printer. Disconnect the power cord and all other cables. (If the double-sided print module is installed, then you must first disconnect rear part and tray.)

2 Unscrew the two clamping screws from the rear surface of the printer.

3 Talk to the protrusions and pull the formatting device on yourself. Place it on an even non-conductive surface.

4 Remove the DIMM module from an antistatic case. Hold Dimm with your fingers behind the sides and thumbs behind the rear edge. Position the grooves on the DIMM module above the DIMM slot. (Make sure that the clamps on both sides of the DIMM slot are open and turned outward.)

5 Insert the DIMM directly into the slot (with pressure). Make sure that the clamps at both ends of the DIMM slot stood in place before clicking. (To remove the DIMM, you must open clamps.) The DIMM module with embedded software must be installed in Slot 1, as shown in the figure. DIMM memory modules can be reinstalled in any other slot different from the first.

6 Set the formatting device to the printer and tighten the two screws firmly.

7 If a two-way print module has been installed, attach back the tray and the back of the module. Connect the interface cables and power cord. Turn on the printer to test the DIMM installed modules.

If the module is a double-sided printing:

1 Pull the rear section of the double-sided printing module from the printer.

2 Remove the rear section of the module, for this you need to raise and turn it in such a way as to release all grips from the grooves, as shown in the figure.

3 Disconnect the power cord and all other cables.

4 Disconnect the tray cable, it must be raised and removed from the groove, as shown in the figure.

Go to action 2.

To install the tray cable and the rear section of the double-sided print module, follow these steps in reverse order. Make sure the tray cable is connected correctly and the cables go through the left side.

Checking the correctness of memory installation

Follow the steps below to make sure that the DIMM modules are installed correctly:

1 Ensure that the inscription is ready to display on the printer control panel display after switching on the printer. If an error message appears, the DIMM module may not be installed incorrectly. Check printer messages.

2 Print a new configuration page.

3 Refer to the Memory section in the configuration page and compare it with the configuration page that you are printed before installing the DIMM module. If the amount of memory has not increased, it is possible that the DIMM module is installed incorrectly (repeat the installation procedure) or faulty (try installing a new DIMM module).

If you have installed a language (or personalization) of the printer, view the "Personalization" section on the configuration page. In this section, information about the new printer language should appear.

Setting Memory Settings

Saving resources

Resource saving mode allows the printer to save downloaded resources (constantly loaded fonts, macro or images) when the printer language or resolution changes.

If there is no additional hard disk or DIMM flash memory or flash memory for storing uploaded resources, when loading unusual large number Fonts or if the printer operates in time separation mode, you may need to change the amount of memory allocated for each language.

The minimum amount of memory allocated to save resources is 400 KB for PCL and as much for PS.

To determine the amount of memory allocated for the language, follow these steps.

1 In the configuration menu, set the sax. resources \u003d incl. You may need to add memory to the printer so that this parameter appears in the printer's control panel.

2 In addition, in the configuration menu, select PCL, memory or PS, memory and set the parameter to maximum valuelisted. This value will vary depending on how the amount of memory is installed in the printer.

3 with help application program Load all the fonts you want to use for the selected language.

4 Print the configuration page. The amount of memory used by the fonts is listed next to the language name. Round this value to the nearest 100 KB. (For example, if 475 KB is shown, 500 KB should be reserved.)

5 In the configuration menu, set the values \u200b\u200bfor PCL, memory or PS, memory equal to the value defined in action 4.

6 Repeat Action 3. (You must download all fonts again, see below.)

When you change the resource saving option, all loaded resources (for example, fonts and macro) must be downloaded again if they are not stored on an additional hard disk or in the DIMM flash memory.

I / O buffer

In order for the computer to continue to work without waiting for the completion of the print job, which is in the queue, part of the printer's memory (I / O buffer) is used to store the tasks performed. (If the I / O buffering mode is turned off, the memory for performing this function is not reserved.)

In most cases, it is best to allow the printer to automatically reserve memory for I / O buffer. (For each megabyte of memory added to the printer, is reserved 100 KB.)

To speed up the network printing, you can increase the amount of memory reserved for I / O buffer.

To change the I / O buffer parameter, follow these steps.

1 In the I / O menu, set the buffer \u003d incl.

2 Also in the I / O menu, set the buffer size equal to the desired value.

When you change the I / O buffer parameter, all

uploaded resources (for example, fonts and macro commands) must be rebooted, if they are not stored on an additional hard disk or in the DIMM flash memory.

Installing large amounts of cards and storage devices

Turn off the printer before installing the boards or storage devices.

To delete files from the storage device, use HP Web Jetadmin. For getting for more information See certificate for software printer.

Select MFP (multifunctional device) for office or home. MFP Parameters affecting the choice: speed, memory, printing resolution and scanner, presence of fax, etc.

MFP or multifunctional devices optimal for use in small offices or home working groups. Having one device capable of printing, send faxes, scan and copy, you can significantly save area and finance.

But not any MFP is suitable for home or for small firms - how to choose MFP? Many of them are not positioned as multifunctional printers capable of performing all 4 functions, but it is not necessary that they are all carried out equally qualitatively.

If you want to buy an MFP with high scan resolution, or you have separate fax requirements, then you need to carefully pick up color MFPs.

No matter whether you choose inkjet MFP for home or laser MFP for office.

MFF speed speed

Many cheap MFPs and a large number of medium price range models happens low speed print or copy, in particular, if you mean color printing.

Choose the highest speed MFP that will suit you at a price. When working, you will certainly feel the difference between printing 12 and 30 pages per minute of MFP.

Memory capacity of MFP

The magnitude of the memory of the multifunction device directly affects its value. If it comes to printing, transferring faxes or copying the documentation, then the lack of memory will immediately be felt.

The memory of 8 MB may be enough to work in a small company or home office.

However, if you have to often work with big documents, or if MFP has many users, you need to think about the acquisition of a multifunctional device that has a memory is not less than 16 MB (although it is better - greater).

The magnitude of the pressure of the MFP

The image quality is better than the larger DPI (the number of points per 1 inch). Resolution standard 600x600 is quite suitable for many types of printing, except for printing photos.

Especially look at the resolution of the scanner, as it is often in multifunctional devices is low. Even pay attention to the high-quality difference between the resolution of the interpolation and optimal.

Fax option in MFP

Check the speed quality fax / modem. In most MFPs equipped with a fax function, fax / modems that have a transmission speed of 33 kbps are integrated, which means faster passage of your faxes on telephone lines, and can be saved on this.

Do not take MFP with slow fax. Carefully look at the functional characteristics of the fax.

If you need a fax with sending function, sending to set time, transmissions on external request, acceptance to a personal box, forwarding to e-mail, SMB, FTP, make sure that the MFP chosen by you possesses these all options. After all, many MFPs do not possess a complete set of facsimile options.

Opt paper

Do not acquire MFP without the availability of a paper feeder (this sometimes happens from a number of cheap models). And to stand all day at the car, feeding into it on the leaf of paper - the pleasure of doubtful.

Purchase MFP, equipped with an automatic paper feeder, which has a capacity, minimum, in 50 sheets. Here the size value is as they say, has.

Precent check of the MFP

In no case should not buy a multifunctional device without checking it pre-in place.

Read the specification and check how MFP behaves during inclusion. Each function, check separately to make sure that the device you selected, meets all your requests.
