Ethernet Printers

Use the following procedure to troubleshoot an Ethernet printer. Troubleshooting is all done

from the Unix system prompt (#).

To troubleshoot an Ethernet printer:

1. At the system prompt (#), enter the following command to determine if the problem

printer is on the network.

ping lp# (where # is the number of the printer)

• If you get a response similar to the response below, the printer is on the network.

Press the Ctrl+Break keys, to stop the command and return to the # sign. Then skip

to step 4.

PING lp3: (90.0.0.21): 56 data bytes

64 bytes from 90.0.0.21: icmp_seq=0 ttl=255 time=18 ms

64 bytes from 90.0.0.21: icmp_seq=1 ttl=255 time=17 ms

• If you get a response similar to the one below, the printer is not on the network. Press

the Ctrl Break keys, to stop the command and return to the # sign. Then proceed

with step 2.

PING lp3: (90.0.0.21): 56 data bytes

2. Check all of the physical connections to the printer (cables, pocket print server or card)

and make sure they are secure.

3. Check the light on your pocket print server or card.

• If the light is red, power off/on the pocket print server. If you have an internal card,

power off/on the printer.

• If the light is green (good connection), repeat step 1 until the printer is on the network

and then continue with step 4.

4. Type lpstat -plp# and press Enter, to get a status on the problem printer.

• If the printer shows there is an active job, stop printing to the printer, as follows, and

then continue with step 5:

• Type enq -DPlp# and press Enter, to bring the printer down.

• Type lpstat -plp# and press Enter, to confirm the printer status is now down.

• Power the problem printer off/on.

• Type enq -UPlp# and press Enter to bring the printer up to a ready mode.

• If there is no active job on the problem printer or nothing printed, continue with step
