Printer driver,Printer drivers in different operating systems

In computers, a printer driver is a piece of software that converts the data to be printed to the form specific to a printers. The purpose of printer drivers is to allow applications to do printing without being aware of the technical details of each printer model.
Printer drivers in different operating systems
Unix
On UNIX systems and other systems which use the Common Unix Printing System, such as Mac OS X, printer drivers are typically implemented as filters. They are usually named the front end of the printing system, while the printer spoolers constitute the back end.
Backends are also used to determinate the available devices. On startup, each backend is asked for a list of devices it supports, and any information that is available.

DOS
On MS-DOS, there have been no system-wide printer drivers; each application was shipped with its own printer drivers, which were essentially descriptions of printer commands. Printers, too, have been supplied with drivers for the most popular applications. In addition, applications included tools for editing printer description, in case there was no ready driver. In the days when DOS was widely used, many printers had emulation modes for Epson FX80 and IBM Proprinter commands. It appears that these also worked with Windows 3.0[2].

Windows
On Microsoft Windows systems, printer drivers make use of GDI (Unidrv or PScript-based) or XPS (XPSDrv). Programs then use the same standard APIs to draw text and pictures both on screen and on paper. Printers which use GDI natively are commonly referred to as Winprinters and are considered incompatible with other operating systems.
Win32 APIs also allow applications to send data directly to the spooler, bypassing the printer driver; however, few applications actually use this option.

Amiga
The original AmigaOS up to 1.3 supported printers through a standard series of drivers stored at the required path "Sys:Devs/Printers". All printer drivers were stored in that directory, and covered the standard printers in 1985-1989 circa, included EpsonFX standard driver, XEROX 4020, HP, etcetera.
Any Amiga printer driver had to communicate though the standard Amiga Printer. Device (the default standard hardware device of Amiga dealing with printers), and the standard Parallel. Device (which controlled parallel port) and the driver would then control the printer on its own.
Amiga printers were an innovation for their time. The had the ability to print up to 4096 colors.
Through the use of the Printer Preferences program printers could be connected to the serial port as well.
Amiga also had support for a virtual device "PTR:" to refer to printer.device so, for example the command "COPY file TO PRT:" caused the file to be printed directly bypassing Parallel. Device and the default Printer Driver. Amiga used a standard ANSI "Esc sequences" list of ESC (Escape) Commands, not the special ones defined by the various printer manufacturers. This way every application on the Amiga could use the same standard set of control sequences and wouldn't need to know which printer is actually connected. The printer driver then translated these standard sequences into the special sequences a certain printer understands.
Amiga internal function "PWrite" of Printer. Device writes 'length' bytes directly to the printer. This function is generally called on by printer drivers to send their buffer(s) to the printer. Number of buffers are decided by the persons who created the driver. Amiga lacked a standard Printer Spooler.
Since AmigaOS 2.0 a standard Printer. Device was changed to control various printers at same time. The Printer preferences were divided in three main panels: Prefs:Printer which selects main printer and other basic elements such as "Print Spacing" and "Paper Size". PrinterGFX controlled features like Dithering and Scaling. PrinterPS controlled Postscript Printers. The printer drivers surprisingly remained almost same of Workbench 1.3, with 4096 limits.
This fact led Amiga users to prefer third party Printer Systems with their own drivers, like TurboPrint and PrintStudio, which introduced not only recent drivers, but also featured a functioning Printer Spooler into Amiga, and featured 16 millions colors printing. MorphOS Amiga clone Operating System uses a special version of TurboPrint to pilot recent printers.
Many Amiga programs like DTP programs as PageStream featured in the past its own printer drivers.
USB printers are automatically recognized by the Amiga USB Stack, which is called Poseidon. This stack is capable of detecting any USB device by its class, but printers still require a driver to be controlled.

PostScript printer description
Usually the operating system needs to know the characteristics of a printer. The PPD files are the normal way to supply this information. They have the advantage of being system independent, and there is a freely available large database of them, Foomatic.

Configure and troubleshoot Print Spooler service

Print Spooler service is required to print documents or to install printers. If the service is not started, then it will instead give an error message (The usual solution is to start the service or clear the spool directory or reinstall printer drivers):
Printer operation cannot continue due to lack of resources. The print subsystem is unavailable

The RPC Server Is Unavailable

Operation cannot be completed.

To configure the priority of the print spooler threads use these DWORD registry values:
[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Control \Print]
SpoolerPriority = 1 (0 = Normal, 1 = Higher, 0xFFFFFFFF = Lower)
SchedulerThreadPriority = 1 (0 = Normal, 1 = Higher, 0xFFFFFFFF = Lower)
PortThreadPriority = 1 (0 = Normal, 1 = Higher, 0xFFFFFFFF = Lower)

To configure the output to the EventLog:

[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Control \Print \Providers]
EventLog = 0 (0 = Disabled, 1 = Errors, 2 = Warnings, 4 = Informative, 7 = All)

To configure whether to make a notify popup when print job finished. Open Control Panel -> Printers -> File-menu -> Server-Properties -> Advanced-Tab -> Untick "Notify when remote documents are printed". (This should be reflected with this registry key)

[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Control \Print \Providers]
NetPopup = 0 (0 = Disabled, 1 = Enabled)

To configure whether shared printers should use bandwidth to announce themselves to the entire network (Internet included):

[HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Control \Print]
DisableServerThread = 1 (1 = Hidden, 0 = Visible in Network Neighborhood)

Brother Printer Drivers - How to Find Brother Drivers the Easy Way

Stressed out because you cannot print from your Brother printer? Sometimes the solutions are easy fixes, such as a paper jam or replacing an ink cartridge. But there comes a time when printers cease to work because of a much deeper issue. This problem is likely driver-related. If you're hooking up the printer to a new machine or you recently installed a new Operating System on your current computer, the two may not be compatible. If you've recently installed new hardware to your computer and subsequently your printer is on the fritz, then the new hardware is likely causing a technological glitch. There are a lot of problems that can occur with your Brother printer and if basic troubleshooting doesn't correct the issue, then a likely fix is to update the driver.

A driver is a library of files that contain the specific code required to carry out actions of the device, your Brother printer in this case. This code is in a universal language so that all other devices and hardware on your CPU can understand it. In a sense, it works as the device middle-man.

Having the most up-to-date Brother printer driver can fix bugs, patch security vulnerabilities, add new features or software, add compatibility to unsupported operating systems, and may offer improved performance. If yours is outdated or corrupted, you may be experiencing poor computer performance, application freezing, and computer crashes.

Whether you're troubleshooting your Brother inkjet, laser, all-in-one, or network printers, you surely know how hard it can be to locate and install the right driver. You can find some driver updates on Brothers website, along with some very long instructions on how to update the driver. There is a lot of manual technical work to be done, something that should be left to someone who is familiar with the inner workings of a computer. The last thing you want to do is poke around in there and mess up your computer.

You need to use driver update software on your system - the software quickly scans for and downloads the correct official printer driver for your Brother printer, or any other device driver on your computer. You do not need to be a professional IT technician to update your device drivers this way. All you need to be able to do is click your mouse and you can use this time- and money-saving software.

Tired of searching for the right drivers? Want to download brother printer drivers EASILY? With this software you can stay on top of driver updates for all your hardware devices. Scan your system for free and up your ALL your drivers automatically!

Printer Repair and Support,How to Troubleshoot Printer Problem

Printer is a peripheral device which is used to take a print or which produces a hard copy of documents. Some printers used as
local and attached with USB cable or parallel ports to the computer. Some printers known as Network printers attached by LAN
cable or wireless. With the help of network printers you can take a print through the network. Individual printers are designed
to support both local and network connected users at the same time. Some printer can directly connect with images capture
devices such as digital camera, scanners. you can take directly print from here. you not need to connect computer with printer.

There are many manufacturer of printer like Hp, Canon, Lexmark etc. There are many types of printer like DMP printer, ink jet
printer, laser jet printer etc. If you are planning to buy any printer for home or office, then you should have some knowledge
about the printer or manufacturer. Like how many pages do you print in per day or month, color print or black and white, quality
of pictures, using of printer means, it will be use in home or office or network and main thinks service of manufacturer

There are some common problems comes in printer like print not coming, spooler service error, system hang when you try to take
any print, document adjustment or half print, error code, paper out message, unable to feed paper etc. These problems comes due
to hardware issue as well as software problems. If you face any type of print problem then first of all you should find which
one is faulty. If paper is unable to feed, that means there is the problem with hardware of printer. But If printer is able to
fire a test page then it may be the problem with software.

There are some common troubleshooting steps regarding printer problem. When print is not coming then, first you should check
that printer is detecting or not. Go to device manager and click new hardware scan. After scanning you should check that printer
is detecting or not in the list. If printer is detected then open the printer and try to print a test page. See the error
messages regarding print.

HOW TO TROUBLESHOOT PRINTER PROBLEMS

1. Printer is on-line or off-line :- The computer cannot communicate or send stuff to a printer that is not on-line.

2. Printers beep :- Most printers will beep once or twice during or after initialization. If it beep continuously that means there is something problem in it.

3. Does it test-print :- Most printers have a built-in diagnostics program which can be very useful for troubleshooting problems and test-printing without a computer.

4. Clean the printer head :- Most ink jet printers have a simple user procedure for cleaning the print heads. You may have to clean them periodically or after the printer has been idle for a few days or weeks.

5. Printer cable :- Check for Printer Cable pins ( bent or not ). Try another cable.

6. Printing from the DOS prompt :- try to print from DOS prompt while printer is not printing from Windows.

7. Check stuck print queue :- Check in printer setting that there is some printing job is still in queue or not. ( Start>Settings>Printers>double click the printer> Printer>Purge Print Documents )


If any message appear on the screen related "spooler service" then, you should check print spooler service from services list. Go to services.msc and start the print spooler service. If printer is not detected then you should change the printer cable and then check. If print stuck in queue then you can open then printer and cancel all the previous document and then try. You should also restart the printer. If all is fine but print is not coming then you can uninstall and reinstall the printer driver software.

Some times you can get error code like:
Error code 02 - It is related to printer warm up issues. If you are facing this, check printer cable for loose connection.
Error code 11 - paper out issue.
Error code 30 - postscript firmware problem.
Error code 14 - check cartridge.
