The NIC's name and IP address must be in this file for the host to answer an RARP request. Many operating systems do not start a RARP server at boot time. Check the host's RARPD documentation for details, or use the ps command to see if there is an RARPD process running. PostScript Problems Area to Check The NIC is communicating with the printer Explanation 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 NIC is communicating with the printer. If the printer is capable of bidirectional communication, use the Test Service PRQLPSEPS_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.
