I need to know if there are any public domain utilities to print
raster files on a postscript printer.  I have a SUN sparc with
a Postscript printer and this is what I have tried:

1.  Create a raster file (RGB-color w/ LUT).

2.  Convert this raster file to a monochrome raster file (w/ LUT).

3.  Type in:  cat mono.ras | pssun -S 7 | lpr

RESULT:  Error, pssun cannot handle raster input of depth > 1.

Well yeah, my depth is 8 bits.  I tried the following which printed
something out, but was of extremely poor quality:

  Type in: cat mono.ras | rasfilter8to1 | pssun -S 7 | lpr

I am not really well-versed with postscript, but I learn fast and if anyone
has a suggestion and/or some public domain filter, I would really 
appreciate it.  Thanks in advance!
