PostScript Print Tool Printing Problems
1. VERIFY that the printer is turned on and connected to a
functioning network port. Check the printer NIC LEDs for
activity. The Link LED should be ON steady, while the Traffic
LED will flicker with activity.
2. At a workstation command line prompt type "ping hostname"
command (where hostname is the hostname of the printer as it
appears in your local /etc/hosts file or your NIS domain host
database. If the "ping" command returns a time-out or failure
you have a communication problem with the printer NIC. Refer
to the TCP/IP Communication Problems section and continue
your diagnostics there.
3. If you are using indirect spooling to print to the printer, VERIFY
that the remote workstation is up and running and can
communicate with the printer NIC.
4. If you are spooling directly to the DocuPrint printer, VERIFY
that you can communicate with the printer. Again, use the ping
command.
5. If the communications test is successful, you may have a
configuration problem at the DocuPrint printer. VERIFY that
LPD is enabled on the printer. The default setting is YES.
6. Use the DocuPrint UNIX software to reinstall a new printer. If
this still fails, call Xerox Technical Support for further
instructions.
