You want something like this in your ifhp.conf:-
gs_device=epsonc
gs_options=-r1440
gs=/usr/bin/gs
gs_converter= [ \%s{gs} -dBATCH -q -sOutputFile=- \
-sDEVICE=\%s{gs_device} \%s{gs_options} - ]
text_converter= [/usr/bin/a2ps -q -B -1 -M Letter \
--borders=no -o- \%s{ps_converter} ]
gzip_decompresser = [ /usr/bin/gzip -c -d ]
[ ghostscript gs ]
file_output_match = [
*postscript* ps \%s{ps_converter}
*text* pcl \%s{pcl_converter}
*gzip_compressed* filter \%s{gzip_decompresser}
]
Printcap entry:
pr:
:ifhp=model=ghostscript,gs_device=laserjet,gs_options=-r300x300
That's from the ifhp HOWTO - it won't work directly as it stands (you'd
need to change the converter specs), but it'll give you an idea. The
printer I set up to do this is elsewhere - I'll post my actual conf file
tomorrow. The ifhp HOWTO tells you how it all works, in the "File
Conversions" bit. It's very flexible - you could set things up so you
can print gzipped PostScript to a PCL only device quite easily if you
felt the need...
HTH
Mike.
