Troubleshooting my network attached printer

Applies To
HPLIP Version: 
All
Printer(s): 
Printers with network capability
Linux OS Distribution(s): 
All
Solution: 

If you are confguring a network printer and are experiencing problems here are some troubleshooting steps.

Does the printer have an IP address?

Ensure that the printer is connected to the network and has an IP address. Refer to your printer documentation for specific information on how to view/configure the printer IP address.

Can you ping the printer?

Open a terminal window and run "ping ip.address.of.printer". If you don't get a response there could be a network configuration problem. If you can't ping the printer HPLIP will not function correctly.

Does running snmpwalk get a response from the printer?

Run:

snmpwalk -Os -c public -v 1 ip.address.of.printer 1.3.6.1.4.1.11.2.3.9.1.1.7.0

You should get a response like (varies depending on the printer model):

enterprises.11.2.3.9.1.1.7.0 = STRING:
"MFG:Hewlett-Packard;CMD:PJL,MLC,BIDI-ECP,PCL,POSTSCRIPT,PCLXL;MDL:hp
LaserJet 3380;CLS:PRINTER;DES:Hewlett-Packard LaserJet
3380;MEM:23MB;COMMENT:RES=1200x1;"

If you do not get this sort of response then there is a problem with your snmp configuration. Ensure that the required dependencies for snmp are installed and/or refer to your distro documentation.

Ensure that the correct ports are open.

Make sure that port 161 (udp and tcp), port 162 (udp and tcp) and port 9100 (udp and tcp) are open through your firewall. If these are not open then HPLIP will not function.
