A Very Important Tool PostScript is a Page Description Language (PDL) that was developed by Adobe. PostScript differs from other PDLs because it treats items on a page as geometric objects. When you print to a PostScript printer, PostScript commands are sent from your system in the form of text commands. This text contains exacting information about what is on the page. The text is received, understood and translated by a PostScript interpreter in your printer. Because of the simplicity of text commands and the consistency of PostScript interpreters, any PostScript printer will print the text information in the same way. Sending the same Postscript information to fifty different printers would yield the same results. PostScript font information follows the same principle which is why designers use them over their inexact counterparts, TrueType fonts. Consistency between your laser printer and a printer's imagesetter is an invaluable thing. PostScript interpreters come standard in Macintosh laser
printers and can sometimes be added to inkjet printers. The interpreters
are less common on the Windows side because the machines are marketed
as business machines rather than design machines. You can usually order
a PostScript interpreter for a Windows laser printer and can sometimes
get them for Windows inkjet printers. If you're not using a PostScript-enabled
printer, your output will not be consistent between other printers and
Postscript-based graphics, like EPS
files, will look terrible. |

ostScript
is the technology that really made the evolution of desktop publishing
into professional design possible. Without PostScript, the computer design
industry would have never gotten off the ground. Before PostScript, designers
working with computers didn't have the necessary control over printed
output that exists today.
