I use one or two extra options with my 895c, but also run it through
lpr/magic-filter so you'll have to extract the parameters from my
gs-aladdin filter file:

# PostScript

0       %!              filter  /usr/bin/gs  -q -dSAFER -dNOPAUSE \
-r300 -sDEVICE=hpdj -sModel=unspec -sColorMode=CMYK -sMediaType=plain \
-sPrintQuality=draft -sOutputFile=\|"cat 1>&3" - 3>&1 1>&2

0       \004%!          filter  /usr/bin/gs  -q -dSAFER -dNOPAUSE \
-r300 -sDEVICE=hpdj -sModel=unspec -sColorMode=CMYK -sMediaType=plain \
-sPrintQuality=draft -sOutputFile=\|"cat 1>&3" - 3>&1 1>&2

# PDF

0       %PDF            fpipe   /usr/bin/gs  -q -dSAFER -dNOPAUSE \
-r300 -sDEVICE=hpdj -sModel=unspec -sColorMode=CMYK -sMediaType=plain\
 -sPrintQuality=draft -sOutputFile=\|"cat 1>&3" $FILE 3>&1 1>&2

I find the dj550c filter suggested earlier is far too inky. Change
draft to normal or best (and set up two queues) if you find draft
is *too* light. The last saves a lot of ink, though.

(One day I'll sit down and try to parse all that output redirection!)

Cheers,
