Troubleshooting Printing Problems

B.5 Printing Problems

	Table B-6:General Printing Problems
Area to Check	Explanation
Physical connections	To test a non-PostScript printer, use the Test Port MPS 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
	MPS 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 problems
	can occur when there are duplicate IP addresses.
Queue Status and Port	Use the Monitor Queue command to ensure queue entries appear
counters	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.

B.5.1 PostScript Problems

PostScript printers will silently abort jobs if they detect an error.

Table B-7:PostScript Troubleshooting

Area to Check	Explanation
The MPS is communicating	To test a PostScript printer, use the Test Port 1 PostScript
with the printer	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	If special characters or bitmaps are not printing correctly, the
use 8-bit characters	printer may be incorrectly configured to use 7-bit characters.
