I think I saw something about an HP printer in your postings. Here is
what I found out recently about some HP printers (mine is a LaserJet
1018 - old but good).
I had been using a Windows as the print server but finally eliminated
that in favour of Kubuntu 10.10. While the Linux printers had no
problem printing from the HP as long as it was on the Windows machine
there was no response when hosted on Linux. I couldn't even print on
the machine where the printer was attached, even though it was
detected by the operating system. I searched and finally found that an
additional HP proprietary driver, hplip, was necessary. I found it on
their website and wasn't hard to install. That could be what you need.
There seems to be the same thing in the repositories but if that
doesn't work try the HP site.
