Printing across different subnets

   Posted by: Dante   in General

When printing across different subnets, or configuring a personal firewall, certain ports need to be opened. For RAW and LPD/LPR printing, use the following:

  • TCP 9100
  • TCP 515

If printing from Microsoft Windows, the operating system will need SNMP access open as well, otherwise the printer detection procedure won’t work. Open the following port:

  • UDP 161

Make sure that the SNMP access is read-only, or that it has a strong password if read-write is really needed.
