Unless your printer is smart about raw ASCII, you can't just send the ASCII to a PostScript printer, because the printer will attempt to interpret your ASCII file as PostScript code. You need a program which will wrap some PostScript code around your ASCII file.
Try any of the following programs: asciiprint.ps, ato2pps, cz, ETSR, i2ps, lpp, lwf, POSTPRN, printer, psf, psfx80, PSR, ps2txt, pstext, swtext, text2ps, TranScript, spike.ps, enscript, nenscript, a2ps, asc2ps, ascii2ps, crossword.ps, double.ps, landscape.ps, numbered.ps, portrait.ps, or wide.ps.
If you want to make something fancy, why not use a word processor? Most of them can ``include'' ASCII directly from a file and produce PostScript.
