MPS/LPS User Guide B: Troubleshooting
B-5
Area to Check Explanation
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 MPS and the
printer.
PostScript Problems
PostScript printers will silently abort jobs if they detect an error.
Table 15: PostScript Troubleshooting
Area to Check Explanation
The MPS is
communicating with
the printer
To test a PostScript printer, use the Test
Port 1 PostScript Count 2 command.
This command will send 2 pages of PostScript
data out the parallel port. Watch the indicators
on the printer to verify that the MPS is
communicating with the printer.
If the printer is capable of bidirectional
communication, use the Test Service
MPS_xxxxxx_PS PostScript Count 5
command. This will transfer data both to and
from the printer. Autoselection must be
disabled and the printer must be configured as
a PostScript printer for this test to succeed.
The printer is
configured to use
8-bit characters
If special characters or bitmaps are not
printing correctly, the printer may be
incorrectly configured to use 7-bit characters.
Service
Characteristics
Issue the Show Service
Characteristics command. If the service
rating is zero, the parallel port is in use. Verify
that the PostScript characteristic and
appropriate protocols have been enabled on
the service.
