PostScript Problems
PostScript printers will silently abort jobs if they detect an error.
Area to Check
Explanation
DHCP is enabled on the network
interface.
Use the Define Server DHCP Enabled
command.
If you manually enter an IP address, DHCP is
automatically disabled.
Make sure the DHCP server is
operational.
Check to see that the DHCP server is on and is
functioning correctly.
Did the network interface get its IP
address from the DHCP server?
Refer to the DHCP Manager on your Windows
DHCP server for information about addresses
currently in use. If the DHCP server does not list
your network interface’s IP address, there many be
a problem.
Area to Check
Explanation
The network interface’s name and
hardware address in the host’s /
etc/ethers file
The network interface’s name and hardware
address must be in this file for the host to answer a
RARP request.
The network interface’s name and
IP address in the /etc/hosts file
The network interface’s name and IP address must
be in this file for the host to answer a RARP
request.
The operating system
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 a RARPD process running.
Area to Check
Explanation
The network interface 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 network interface 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.
