Default printer ports?

Hello-

I have a printer that is currently located on the same subnet as my HP-UX 11.11 servers.  That printer is going to be moved to another location and will have a different IP address on another subnet.  I suspect that I will need to submit a firewall request to open up communication between my servers and the printer.  Can anyone tell me the default port(s) that will need to be opened for this?

 

TIA

Printers usually communicate on TCP port 9100 if you're using HPPI (formerly the Jet Direct software) from the HP-UX server.

If the printer is connected with an HP LAN card in the printer or is using an external HP LAN-to-printer adpater, then port 9100 is used. For almost all non-HP printers and LAN adapters, the port is 515.

Re: Default printer ports?

You can check the printer configuration and its model , depending on the type of printer it will listen on the respective port, 

For hp-ux default models like rmodel /dumb it  needs to  listen on the port 515/tcp , if it is jetdirect printer model and using 'HP Jetdirect software' it needs to listen on port 9100 .

 

Please check with # lpstat -t  -d <printer_name>  

 

Check /etc/services for printer entry to check for the printer port : 
# cat /etc/services | grep printer

 

Hth,
