Aaargh. Don't dither the image with rastfilter8to1 and only send 1-bit data
to the postscript printer. Send the printer 8-bit data and let it do the
dithering.
Use psraster (anonymous ftp from titan.rice.edu: /sun-source).
However psraster has a bug in that it does not reclaim it's VM and will
run out for large images. Apply this diff:
yourhost% diff psraster.c.orig psraster.c
194c194
< fprintf( outfile, "{GetImageRow} image\n");
---
> fprintf( outfile, "{restore save GetImageRow} save 6 1 roll image\n");
screendump | psraster | lpr
Even sexier is: dumpregion | psraster | lpr
dumpregion is also available from titan.rice.edu.
Good luck,
