Table B-5: General Printing Problems
Area to Check Explanation
Physical connections To test a non-PostScript printer, use the Test Port Server
Count 100 command. This command will send 100 lines of
test data out the parallel port so you can see if the printer is
receiving data.
Service characteristics Use the Show Service Local Characteristics command
from the Server Local> prompt to see if the desired service
is available and to verify that the appropriate protocols are
enabled on the service.
The IP address The IP address must be unique on the network. Many prob-
lems can occur when there are duplicate IP addresses.
Queue Status and Port
counters
Use the Monitor Queue command to ensure queue entries
appear in the job list.
Use the Monitor Port 1 Counters command to verify that
the counter is incrementing with each job. If it is not, verify
the connection between the Server and the printer.
