No output when printing from Unix
If you encounter “no output” problems when printing from Unix, try
the following:
1. Check the printer hardware.
•
Check that the printer is plugged in and turned on.
• Check that the cable is connected to the port on the printer
and the port on the workstation or server.
• Check that the cable is the correct cable and is not defective.
• If the printer is connected to a serial port, make sure the cable
supports hardware flow control. A NULL modem adapter
supports this.
• Check that hardware switches for the port are correctly set.
• Use the printer’s self-test feature or run the demo print to
assure that the printer is functioning.
• Check that the baud settings for the computer and printer are
correct. If the settings do not match, the file may be printed
incorrectly or not at all.
2. Verify network connections.
• On a print client or server, type ping system-name and press
Return. This command checks that the network link between
the print server and print client is set up correctly.
If the message says the system is alive, the network is func-
tioning. The message also tells you that either a naming
service or the local /etc/hosts file has translated the host
(system) name entered into an IP address. If it hasn’t, you
must enter the IP address.
• If you get a “not available” message, check the following:
• How is NIS or NIS+ set up at the site?
• Do you need to take additional steps to allow the print
servers and print clients to communicate with each other?
• If your site is not running NIS or NIS+, have you entered
the IP address for the print server in each client’s /etc/
hosts file and entered all print client IP addresses in the /
etc/hosts file of the print server?
