PostScript Troubleshooting 

Area to Check

Explanation

The Server is communicating 

with the printer

To test a PostScript printer use the Test Port 1 PostScript Count 

2

. This command will send 2 pages of PostScript data out the 

parallel port. Watch the indicators on the printer to verify that 

the Server 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 

conÞgured as a PostScript printer for this test to succeed.

The printer is conÞgured to 

use 8-bit characters

If special characters or bitmaps are not printing correctly, the 

printer may be incorrectly conÞgured 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.
