How do I change a printer’s IP address in Linux?

The mappings of IP addresses to “lp” names are contained in the /etc/hosts configuration file. You may modify the IP addresses for entries in the /etc/hosts files in a couple of different ways:

Command Line

  • Log into your server via PuTTY
  • Launch your favorite text editor to edit the hosts file. For example, using vim:
vim /etc/hosts
  • Locate the entry for the printer(s) you wish to change
  • Make the change
  • Save the file and quit

GUI

To change the printer’s IP address from the GUI interface:

  • Log into the GUI via any method (ie VNC, DRAC, physical console)
  • Navigate to Applications -> Accessories -> Text Editor
  • Navigate to File -> Open Location
  • Enter /etc/hosts
  • Locate the entries for the printer(s) you wish to change
  • Select Save
  • Exit

How do I troubleshoot a Linux printer

To troubleshoot a print queue on Linux:

  • Log into the server as root
  • Try to ping the server:
ping -c4 lp1
  • Common problems:
    • If the printer doesn’t respond, verify its network connectivity
    • If the printer exhibits packet loss or high latency (round trip) times, check with your network support provider, as these can disrupt printing
  • Check the Linux (CUPS) print queue status:
lpstat -p lp1
  • Common problems:
    • If the printer is “disabled” or “paused,” enable the queue: cupsenable lp1
  • Check the UniVerse (UV) print queue status:
usa -p lp1
  • Common problems:
    • If the printer is marked as “off,” enable the queue: usa +o -p lp1
