Yes. Sugar, milk, and Bovine Growth Hormone, which is why there
is a lot of ... umm... B.S. on the net lately :-) --- sorry,
I could not help it...

I stared and stared and stared at this for an hour.
Ummm... modify your ifhp.conf file, and change the
following entry, and then see if it works correctly.
It appears that PCL must be 'raw' for these printers:
[ pcl_gs ]
status@
pjl@
pcl
ps@
text@
gs_device=ljet4
file_output_match = [
*pcl* raw
*text* pcl <--- this forces the correct operation for
<--- text files.
# postscript to PCL conversion
*postscript* raw \%s{gs_converter}
*gzip_compressed* filter \%s{gzip_decompress}
]
