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.
