Laserjet Printers

Hi,

I have two HP Laserjet printers (HP4000n & HP1200) each
is attached to different types of print servers on my
LAN. The HP4000 uses a built-in print server from HP and
the HP1200 uses an external print server. I'm using
Windows XP Pro; with all svc packs and critical updates
installed.

My problem is when I print to either one of the printers,
the job prints just fine, however, the print job stays in
the print queue. If I disconnect from the network and
reconnect, then the print job, that stayed in the queue,
prints again. I have to go out and manually delete the
print job(s) from the queue. I have other printers on
the network (Lexmark) and it works fine, with none of the
problems as described above.

I also have other workstations on the LAN mixed XP Pro
and Windows 2000 Pro, none of these computers experience
the problem with any printers.

I've downloaded and re-installed the drivers from HP for
both the PCL6 and PCL5-e formats. Still with the same
results. I've contacted HP support and they say that
since the printers work well with other similar
workstations on the LAN, then it must be something
with "Windows". That's what brought me here, can anyone
help with this issue. I would certainly appreciate your
efforts.

Thanks
John Daigle
