I.6 PostScript Problems

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

Table I-6:  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 EPS_xxxxxx_PS PostScript Count 5 command. This will 

transfer data both to and from the printer. Autoselection must be dis-

abled 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 rat-

ing is zero, the parallel port is in use. Verify that the PostScript charac-

teristic and appropriate protocols have been enabled on the service.
