Grey scales look rubbish. In ram limited printers, host based print processors are usually at least twice as fast to finished output as PCL or PS. Cause the RIP process in the printer goes terribly, terribly wrong. This phenomena is usually exacerbated on printers with less the MB of ram. Thu Apr 21, 4: Post Falls, ID Registered: I ran into these two while looking for a printer driver, and I haven’t been able to determine which is best for my needs.

These commands provide a printer with the ability to change modes so that it behaves just like a printer from another manufacturer. I avoid them like the plague and would only use a PCL or Postscript printer because while you might lose some high level functionality if you have to use a different driver you should always be able to print to them whereas with a GDI printer you are SOL if you don’t have an exact driver for your OS.

Post Script can be used by a wide variety of computers and printers and is the dominant format used for desktop publishing.

OKI News: What are the differences between GDI, PCL and Post Script printers?

One thing worth mentioning in favor of gdi or “host based print processors”, the rasterising of prknter images also occurs on the PC as opposed to in the printer’s print server resulting in smaller jobs, less network traffic, and speedier, MUCH speedier print jobs. GDI printers are the ones that always cause people issues when they priter OS’s or switch to using a MAC or Linux because while they may be occasionally supported they most often are not.


Usually, PCL has a cool little settings, where they straddle both models, one where you rasterise on the computer itself Raster setting in the driverand two, where the vector drawing is rasterised on the printer’s prlnter server GL2 setting in the driver. This is where you’re using a Postscript or PCL driver and relying on the printer’s built in “RIP process” to changed the graphic elements from vectors to bitmaps.

You spend loads and loads on toner, breaking any budget advantage you might have had using cheap printer in the first place.

GDI Vs. PDL – Ars Technica OpenForum

They contain only a rudimentary processor and rely on the host based driver to do their layout work. This is a page description language developed by Adobe Systems.

Thu Apr 21, 1: Shorthand for G raphical D evice I nterface, this is a Windows standard for representing graphical objects not text and transmitting them to output devices such as monitors and printers. Here are a few common emulation command formats: The following information is provided as is, and the authors take no responsibility for the correctness.

Course I pretty much work with monochrome printers, so there you go. GDI printers are also known as win printers. SLX Used by the Lexmark cn.

Printers use a set of operating commands that determine how data sent from the computer printef interpreted and acted upon. PS drivers are without a doubt, the slowest drivers in existence.

PCL importance in choosing laser printer

Functional Test Suites FTSs verify major functions of your emulation, as a quick check before running a CET, to verify minor firmware upgrades, or as a pdll final check. Grey scales look rubbish. If the file to be printed contains an EPS-embedded file, only a Post Script printer can render it correctly. Switching the driver to raster, causes the rasterisation to occur on the PC and usually fixes the grey scale issues. Pinwriter NEC Pinwriter, 24 wire dot matrix printer.



I ran into these two while looking for a printer driver, and I haven’t been able to determine which is best for my needs. Relying on the printer to do the rasterising usually results in identical print output from various drivers on various platforms, which most people consider a “win”.

Dec 22, Posts: Cool new feature, in Windows Server you can force the rendering on the client saving your windows prinrer share server some cycles.

Mon Apr 25, 6: Might be worth telling us the make and model of the printer. PageSense automates printer performance testing and provides standardized results. So far as I can tell GDI is something which sort of predates PCL on Windows and is considered inferior, but information on PDL seems to printeg deal with it as a concept rather than any specifics as printrr what it does as a printer driver.
