Following is a Turbo-Pascal program which was posted to the net some time
ago.  It isn't perfect, but it does a pretty good job of translating files.

--------------- cut here ---------------
PROGRAM Postscript;

{$U+}

{ASCII menu driven listing program that generates PostScript
commands to the Apple LaserWriter.  Allows selction of
bold and normal fonts, font size and line spacing.  Output
can go to a disk file (output.ps) or directly to the printer.

Limitations: Handling tabs is limited to move to an absolute
location on the line.  Program is not smart about the actual
widths of characters in different fonts... it just uses an
average width per character of fontsize/2.  Program cannot
handle tabs and font change escapes on the same line.  Epson
font change escapes ESC G for bold and ESC H for normal are
used.  Bold font and normal font do not mix too well on the same
line.  Spacing for a tab is based on an average of 8 nominal
characters... as a result the tab spacing after some text with
capital letters may not be wide enough and the text starting
after the tab may overlap with previous text.  (On the other
hand, the worst case width of 8 characters is too large for
normal use).

Can be invoked with filename as a parameter: nlist filename
