Printer on thin client network--says it's working but isn't

Tue Sep 22 19:07:48 BST 2009

Hi Dean,

Thanks for your suggestion.  It sounds like you are giving directions to run
the printer on the network THROUGH a local connection to a computer on the
network--a thin client in this case.  This gets me back to one of my main
confusions--there is lots of documentation that says you have to set up your
printer this way, locally connected to the server or to a client on the
LAN.  Other info (fewer pages I've found) tells how to connect the printer
to the LAN directly (through a switch).  I want to connect this old HP 8000
directly to the LAN, not through another computer.  Has anyone else had this
issue?

Thanks,
David
