Unpack everything in /

  Because of the paths compiled in the binaries, this package MUST be
  unpacked in /usr, or symbolic links have to be produced. Of course,
  you can also set the right environment-variables, but beware, there are
  a lot of them, and the intention of this package is just to provide a
  plug-and-play solution to TeX-printing.

Add /usr/local/bin and /usr/TeX/bin to your PATH, if not already there.

Edit a few places to support your printer:
(if you incidentally have a HP-Deskjet compatible with A4-paper inside,
 known to your Linux-Box as /dev/lp1 -- as I do -- you may skip this step ;-)
 1) First look up /usr/local/lib/ghostscript/doc/device.lst to find
    your particular printer (or a compatible one). If it's not there
    you're out of luck.
 2) In /usr/local/bin/gspr change -sDEVICE=deskjet to
    -sDEVICE='your device name found in step 1)'
 3) In /usr/local/bin/gspr change -r300 to -r<res> or -r<xres>x<yres>
    corresponding to the horizontal and vertical resolutions of your
    printer in dots_per_inch.
 4) In /usr/local/bin/gspr change -sPAPERSIZE=a4 to your papersize, if
    yours is different (a list of known sizes can be found in
    /usr/local/lib/ghostscript/doc/use.doc)
 5) In /usr/local/bin/gspr change -sOutputFile=/dev/lp1 to the device
    your printer is hooked up to. If you do not want to use a raw device,
    but a spooler like lpr instead, read /usr/local/lib/ghostscript/doc/use.doc
    to learn how to do that. Beware, Ghostscript may produces HUGE files,
    It sends effectively a bitmap to the printer.
 (Now Ghostscript is ready to go. If you have a Postscript file say foo.ps,
  try gspr foo.ps and it should get printed.)
 6) Look up the Metafont mode-description name of your printer in
    /usr/TeX/lib/mf/macros/modes.mf. Look for a mode_def which has
    a comment (everything from % to end of line is a comment) stating
    the name of your printer. For HP Laserjet e.g you'll find CanonCX
    as the appropriate mode name.
    If you don't find one try at least one with the same horizontal and
    vertical resolution as yours. The rest is not THAT much important.
    Output may look sloppy but readable.
 7) In /usr/TeX/lib/ps/config.ps change the Line D 300 to D <res>,
    the resolution of your printer in dpi, or to
    X <xres>
    Y <yres>
    (on two lines) if horizontal and vertical resolutions differ.
 8) In /usr/TeX/lib/ps/config.ps add the line
    M your_printer_mode
    where your_printer_mode is the mode-description name for your printer
    you looked up in step 6)
 9) In /usr/TeX/lib/ps/config.ps change your Paper size information, if
    youre not using A4, i.e. either comment out the A4size definition and
    uncomment (=remove the starting stars) the letterSize definition,
    if that's the right one, or comment out the A4size definition and
    add your own in front, something like
    @ myownSize hor_size ver_size
    @+ %%PaperSize: myown
10) Make /usr/TeX/lib/tex/fonts/pk world writeable by issuing
    chmod a+w /usr/TeX/lib/fonts/pk. That is necessary
    to enable everyone to use the automatic font-generation feature.

Thats it.
