print filters for PostScript printers

[Antonio Querubin]

I'm looking for some printing filters for PostScript printers (most of the
printers are LaserWriters) that will allow me to print plain text files.  Are
such things available (preferably public domain) and where can I find them?

If not, are there any text to PostScript conversion programs out there?

Also, does anyone have bare-bones source code for a sample input filter?  I may
need to do a little hacking to make a Talaris look like a LaserWriter.

Thanks in advance!
