For an overview of Ghostscript and a list of the documentation files, see README. Generally used system files --------------------------- gs_init.ps - Ghostscript reads this automatically when it starts up. It contains definitions of many standard procedures and initialization for a wide variety of things. gs_btokn.ps - gs_init.ps reads this in if the btoken feature is included in the configuration. It provides support for binary tokens. gs_ccfnt.ps - gs_init.ps reads this in if the ccfonts feature is included in the configuration. It provides support for compiled fonts. gs_fonts.ps - gs_init.ps reads this in. It initializes Ghostscript's font machinery and provides some utility procedures that work with fonts. gs_statd.ps - gs_init.ps reads this in. It creates a dummy statusdict and some other environmental odds and ends for the benefit of PostScript files that really want to be printed on a LaserWriter. gs_dps1.ps - gs_init.ps reads this in if the dps feature is included in the configuration. It provides support for various Display PostScript and Level 2 features. gs_lev2.ps - gs_init.ps reads this in if the Ghostscript interpreter includes Level 2 PostScript functions. It contains definitions of procedures and miscellaneous initialization for the Level 2 functions. gs_res.ps - gs_init.ps reads this in if the Level 2 resource machinery is included. Currently, this is the case for all Level 2 configurations. gs_type1.ps - gs_init.ps reads this in if the Ghostscript interpreter includes Type 1 font capability (which it normally does). gs_*_e.ps - These files define the Encodings known to Ghostscript. All of them except gs_std_e.ps and gs_iso_e.ps are loaded only if referenced. More obscure system files ------------------------- gs_cmdl.ps - This file is not used yet. Eventually it will replace C code that parses the Ghostscript command line. gs_diskf.ps - This file implements the -dDISKFONTS feature (diskfont.dev). See use.txt for a description of this feature. gs_kanji.ps - This file provides support for the Wadalab free Kanji font. It is not included automatically in any configuration. gs_pdfwr.ps - This file contains some patches for providing information to the pdfwrite driver. It is included only if the pdfwrite driver is included. gs_pfile.ps - This file provides runtime support for packed fonts. It is not included automatically in any configuration. PDF-specific system files ------------------------- gs_pdf.ps - The ProcSet that provides runtime support for PDF files. pdf2ps copies this into its output. gs_l2img.ps - The ProcSet that emulates the PostScript Level 2 'image' operator on Level 1 systems. pdf2ps copies this into its output if the PSLevel1 option was selected. pdf_2ps.ps - The additions to the PDF interpreter that allow it to convert PDF to PostScript. pdf_base.ps - Utilities for interpreting PDF objects and streams. pdf_draw.ps - The interpreter for drawing-related PDF operations. pdf_font.ps - Code for handling fonts in PDF files. pdf_main.ps - Document- and page-level control for interpreting PDF files. Art --- chess.ps - A black-and-white chessboard. golfer.ps - A gray-scale picture of a stylishly dressed woman swinging a golf club. escher.ps - A colored version of a hexagonally symmetric Escher drawing of interlocking butterflies. Can be printed on monochrome devices, with somewhat less dramatic results. cheq.ps - A chessboard "font" used by chess.ps (obtained from the Adobe file server). snowflak.ps - A rectangular grid of intricate colored snowflakes. (Renders very slowly.) colorcir.ps - A set of nested ellipses made up of colored bars. tiger.ps - A dramatic colored picture of a tiger's head. Utilities --------- For more information on these utility programs, see the comments at the beginning of the files. The ones marked with * have batch files or shell scripts of the same name (e.g., bdftops, bdftops.bat) to invoke them conveniently. align.ps - a test page for determining the proper margin and offset parameters for your printer. bench.ps - a file useful for running benchmarks. * bdftops.ps - a utility for converting BDF fonts to outline form: see fonts.txt for more information. caption.ps - a file for putting a caption in a box at the bottom of each page, useful for trade show demos. docie.ps - an emulation of the CIE color mapping algorithms. * gslp.ps - a utility for doing "line printing" of plain text files. impath.ps - a utility for reconstructing outlines from bitmap images, used by bdftops. landscap.ps - a file that you can put in front of your own files to get them rendered in landscape mode. level1.ps - a file that turns off any Level 2 features. packfile.ps - a utility for compressing fonts into a single file. prfont.ps - a utility to print a font catalog. * ps2ascii.ps - a utility for extracting the ASCII text from PostScript source files. It redefines many operators. For more information, see the comments in the file. ps2ai.ps - a utility for converting an arbitrary PostScript file into a form compatible with Adobe Illustrator. NOTE: ps2ai doesn't work properly with Adobe's Helvetica-Oblique font, and other fonts whose original FontMatrix involves skewing or rotation. * ps2epsi.ps - a utility for converting an arbitrary PostScript file into EPSI form. quit.ps - a file containing just the word "quit". (The -c switch now makes this unnecessary; this file exists for backward compatibility.) rollconv.ps - a utility for converting files produced by Macromedia's Rollup program to a Type 0 form directly usable by Ghostscript. showpage.ps - a file containing just the word "showpage". (The -c switch now makes this unnecessary; this file exists for backward compatibility.) viewcmyk.ps - a utility for displaying CMYK files. viewgif.ps - a utility for displaying GIF files. viewjpeg.ps - a utility for displaying JPEG files. viewpcx.ps - a utility for displaying PCX files. viewpbm.ps - a utility for displaying PBM/PGM/PPM files. waterfal.ps - a utility to print a "waterfall" of fonts at different sizes. Development tools ----------------- acctest.ps - a utility that checks whether the interpreter enforces access restrictions. decrypt.ps - a utility for decrypting the eexec section of a font. markpath.ps - a utility for showing the points on a path. pcharstr.ps - a utility for printing out the CharStrings and Subrs in a Type 1 font. ppath.ps - a couple of utilities for printing out the current path, for debugging. traceop.ps - a utility for tracing uses of any procedure or operator for debugging. type1enc.ps - the Type 1 font format encryption and decryption algorithms, written in PostScript. uninfo.ps - some utilities for printing out PostScript data structures. unprot.ps - a prologue to disable access checking. viewps2a.ps - a utility for displaying the output of ps2ascii.ps. winmaps.ps - a utility for creating mappings between the Adobe encodings and the Microsoft Windows character sets. wrfont.ps - a utility for writing out an unprotected Type 1 font, such as the standard Ghostscript fonts. zeroline.ps - a utility for testing how interpreters handle zero-width lines. Odds and ends ------------- lines.ps - a test program for line joins and caps. type1ops.ps - the Type 1 font format opcodes.Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
