We have set up our Jetdirect this way.  The Jetdirect card needs an IP
address if it is on a TCP/IP network (which I presume your Linux box is on
too).  Once the IP address has been assigned, the Jetdirect acts like a
standalone lpd to whcih you can feed data from a Linux printqueue.  There
are a couple of tricks to making it work properly.  One is to make sure
that you have turned off the header page (I had to upgrade the Jetdirect
firmware to do this).  The other is to have the proper queue name in your
printcap.  I have enclosed mine below:

lj4m|ls178_hp4m|First Floor Department LaserJet:\
         :lp=/dev/null:\
         :rm=xxx.xxx.xxx.xxx:\
         :rp=text:\
         :sd=/var/spool/lpd/ls178_hp4m:\
         :sh:pw#80:pl#66:px#1440:mx#0:\
         :af=/var/log/lp-acct:\
         :lf=/var/log/lp-errs:

Once you have the queue established, you can serve it to any Windows95
machines on the network by using samba.

I am not aware of any way of getting around the requirement of having an
IP number for the Jetdirect.  You could always connect the preinter
directly to the parallel port of a Linux box and then set up a queue and
serve it to the rest of the network.  I have done this with a
non-Jetdirect HP LaserJet but I much prefer the jetdirect solution.

Good Luck,

Carlo
