Thu Apr 21, 1: Cause the RIP process in the printer goes terribly, terribly wrong. In the case of Postscript drivers, in my experience not that broad, fair enough , the vector is only rasterised on the printer. Mar 12, Posts: 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”.

Each format has its own unique purpose. So if you have thousands of printers and a small pipe, clearly the way to go. They contain only a rudimentary processor and rely on the host based driver to do their layout work.
GDI printers are also known as win printers. Apr 22, Posts: Here are a few common emulation command formats: QualityLogic provides software testing and quality assurance services, as well as test tools for driver and printer description languages. 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 only deal with it as a concept rather than any specifics as to what it tdi as a printer driver.
PCL importance in choosing laser printer
PageSense automates printer performance testing and provides standardized results. Shorthand for P rinter C ontrol L anguage, this defines a standard set of commands enabling programs to communicate with HP or HP-compatible devices. The following information is provided as is, and the authors take no responsibility for the correctness. In ram limited printers, host based print processors are usually at least twice as fast to finished output as PCL or PS.
This phenomena is usually exacerbated on printers with less the MB of ram. Thu Apr 21, 1: You spend loads and loads on toner, breaking any budget advantage you might have had using cheap printer in the first place. 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 cost-effective final check.

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. Post Falls, ID Registered: Usually, PCL has a cool little settings, where they straddle both models, one where you rasterise on the computer itself Raster setting in the driver gdk, and two, where the vector drawing is rasterised on the printer’s print server GL2 setting in the driver.
These commands provide a printer with the ability to change modes so that it behaves just like a printer from another manufacturer. Printer Language Comprehensive Emulation Tests CETs validate your printer’s emulation compatibility with industry standards by thoroughly testing each command in the emulation. This is a page description language developed by Adobe Systems.
I hear some OEMs will start embedding XPS into the rip process on the printers sometime soon too, or maybe MS is just tooting a non existent, as far as I can tell, horn.
Post Script can be used by a wide variety gvi computers and printers and is the dominant format used for desktop publishing.
Might be worth telling us the make and model of the printer. PS drivers are without a doubt, the slowest drivers in existence. Aug 14, Posts: In the case of Postscript drivers, in my experience not that broad, fair enoughthe vector is only rasterised on the printer.
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. Post Script is often used to share documents on the Internet because of this ability to pfl on many different platforms and printers. Switching the driver to raster, causes the rasterisation to occur on ot PC and usually fixes the grey scale issues.

Cool new feature, in Windows Server you can force the rendering on the ppdl saving your windows print share server some cycles. Course I pretty much work with monochrome printers, so there you go. Grey scales look rubbish. 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.
