CUPS Printer Browsing in RHEL 7

Solution Verified - Updated -

Issue

  • CUPS daemon does not "discover" available network printers.
  • How to configure /etc/cupsd.conf so that CUPS will discover networked printers. We have a number of Lexmark laser printers available on our network. I use them with my other RHEL 6.5 hosts just fine, but this RHEL 7.1 host does will not "discover" any available networked printers.
  • I tried adding BrowsePoll printserver:631 to my cupsd.conf file but that throws an error about an unrecognized directive.

Environment

  • Red Hat Enterprise Linux (RHEL) 7 and 8
  • Common Unix Printing System (CUPS) 1.6.3 and 2.2.6
  • CUPS print servers running on other RHEL 4, RHEL 5, and RHEL 6 systems
