Re: DeskJet 870
Thanks to all your tips I've been able to atleast make the printer (and
Linux) realize there are jobs to be printed. It even does color under
Linux. Only problem left is the thing spits out blank pages if I'm printing
from a Winblows station through Samba. In the past, I've had a DeskJet 520
working through Samba without incident.
