+ **************************** Intro *********************************
+ **********************************************************************
+ * This program translates TeX's DVI-Code into device dependent
+ * code of either the
+ *
+ * - HP-LASERJET+ and compatibles (PCL), or the
+ * - IBM 3812 pageprinter
+ *
+ * depending on the preprocessor switches specified before compilation.
+ * The program is written to run on a PC XT/AT/PS2 under MS-DOS. It can
+ * be compiled nicely with MSC Rel. 3.0-5.1 with option -AL (large memory
+ * model). Take care that in the CONFIG.SYS file the FILES parameter
+ * is set to 20; otherwise reduce MAXOPEN. 640K are recommended.
+ * I use link option /stack:9000 to increase runtime stack.
+ * It also works without modifications under Unix System V.

+ * +3812 support Augasse 2-6
+ * +Output buffering A-1090 Vienna, AUSTRIA
+ * +lpt binary support Tel. *43-222-340525/533
+ * +pk-89 stuff 773
+ * +pixelpaths
+ * +alternative directory structure
+ * +code compiles also under Unix V (HP/UX)
+ * (thx Michael Haberler)
+ * +huge characters (a character bigger than 32K)
+ * formats PXL1001 and PXL 1002
+ * (use: raster graphics)
+ * +reduction of the produced code
+ * +new options -X -Y -c -g
+ * +changed options -r (LJ now default from first to last)
+ * -x,-y (accept floats)
+ * +new option -z for LJ: print testpage containing
+ * pagecounter after printjob
+ * +try to overcome font limit on LJ (max 16 fonts/page) and
+ * (max 32 fonts/document):
+ * additional fonts are drawn as bitmap-
+ * graphics.

+ **********************************************************************
+ * fixes in LJ-mode: rule-drawing,
+ * characters with 127<=height<=200
+ * reset printer at beginning and end of each job
+ * better positioning of rules
+ * 30.1.89 (0.48) bug fixed for files containing >32 fonts (thanks A. Brosig),
+ * different font assignment heuristic
+ * fixes in 3812-mode: 14.juli 87 positioning of rastered characters
+ * better positioning of rules
+ * general fixes
+ * 1.1.88 page origin set to 1in/1in (hopefully everywhere)
+ * 22.7.88 reset y-position for each page-eject
+ * 15.1.89 fixing bug is space allocation for EmitFileName
+ * (thanks to Bernhard Simon)
+ * 15.3.91 (0.49) landscape support for lj ii p, lj iii and lj 2000
+ * fixing rule drawing problems for IBM3812 in landcape mode,
+ * 256 character clean (lj family and IBM3812)
+ * 5.5.91 (0.50) -DSEVENBIT added for older LJ-emulations
+ * -D1, -D2, -D-, -D1-, -D2- options added due to suggestions
+ * from Tomasz Wolniewicz
+ **********************************************************************
+ * Preprocessor switches:
+ * #define DEBUG for massive printing of trace information
+ * when -d cmdline option specified
+ * #define IBM3812 produce output for the IBM3812 pageprinter
+ * #define LJ produce output for the HP Laserjet+ or LJ II
+ * #define LJ2P produce output for the HP Laserjet LJ IIP, LJ III
+ * or LaserJet 2000
+ * #define LJ_LARGE_FONT_MEMORY large FONT Memory for LJ printer family
+ * #define DRAWGLYPH draws PK-Glyphs on stderr
+ * #define USEPXL use PXL and PK fonts rather than gf fonts

+ * Germany
+ * dehmel@informatik.tu-muenchen.de
+ *
+ * Changes:
+ * - Split the whole thing up into smaller files
+ * - Rearranged certain parts of the output
+ * - If fonts are missing a taskobey file is created that
+ * contains MF commands to build the fonts.
+ * - SUPPORT FOR DIAGRAMS AS USED IN DVIVIEW!!!
+ * - Fixed problem of raster chars being scrambled when diagram
+ * printouts were on the same page.
+ * - Raster chars and fonts can now also be downloaded in
+ * compressed format; many thanks to Karl Berry!
