![]() Support for version 3.1 of the Document Structuring Convention, described in the PostScript Language Reference Manual published by Adobe Systems, Inc. Support for all PostScript printers, using printer-specific PPD-based Pscript minidrivers that describe each printer's characteristics.Ī Pscript user interface, based on the TreeView control and property sheets, that is consistent for all printers, but is also modifiable for each printer's unique options.Ī single Pscript renderer that, along with the GDI graphics engine, converts Microsoft Win32 GDI calls from applications into printer commands that can be sent to the print spooler. PostScript 3, release in 1997, supports more fonts, better graphics handling, and includes several features to speed up PostScript printing.The PostScript Printer Driver (Pscript) provides the following capabilities: Level 2 PostScript, which was released in 1992, has better support for color printing. ![]() There are three basic versions of PostScript: Level 1, Level 2 and PostScript 3. If your laser printer does not come with PostScript support, you may be able to purchase a cartridge that contains PostScript. A bit-mapped image looks the same on both printers.Įvery PostScript printer contains a built-in interpreter that executes PostScript instructions. A PostScript drawing looks much better when printed on a 600- dpiprinter than on a 300-dpi printer. The principal advantage of object-oriented ( vector) graphics over bit-mapped graphics is that object-oriented images take advantage of high-resolution output devices whereas bit-mapped images do not. To print a bit-mapped typeface with different sizes, these printers require a complete set of bit maps for each size. In contrast, many non-PostScript printers represent fonts with bit maps. Given a single typeface definition, a PostScript printer can thus produce a multitude of fonts. They are also called scalable fonts because their size can be changed with PostScript commands. PostScript fonts are called outline fonts because the outline of each character is defined. ![]() PostScript is an object-oriented language, meaning that it treats images, including fonts, as collections of geometrical objects rather than as bit maps. PostScript is an Object-Oriented Language PostScript is the standard for desktop publishing because it is supported by imagesetters, the very high-resolution printers used by service bureaus to produce camera-ready copy. ![]() It is primarily a language for printing documents on laser printers, but it can be adapted to produce images on other types of devices. PostScript is a page description language (PDL) developed by Adobe Systems. ![]()
