What is your "raw" data? Do people always spool only Postscript,
plain text, and PCL? What will happen on your current setup if I try
lp -d <some_raw_spooled_to_jetdirect_printer> foo.dvi
or
lp -d <some_raw_spooled_to_jetdirect_printer> foo.pdf
?
At work we have some jetdirect boxes too, and I found that I _can't_
send a PDF file directly with 'lp', if I set my spool to raw. The
reason being that the JetDirect box is a spooler, not a converter. It
doesn't convert the PDF to PS or PCL first, thus the printer spews PDF
code. If I set the driver/filter to a certain printer, then CUPS will
convert from PDF to a format the printer can handle and then hand off
the data to the JetDirect box for spooling. (admittedly we have
low-end jetdirect boxes and those are the only ones I have experience
with).
I think you'll want to set up either
a) the printer type on each workstation
or
b) a server to mediate between the workstations and the jetdirect
box to convert from whatever data format the user wants to
throw at it to a data format the printer can actually
understand
(now I want a filter that automatically converts dvi->ps, but maybe
some other day ...)

You're welcome.
