36.2. Adding an IPP Printer

An IPP printer is a printer attached to a different Linux system on the same network running CUPS or
a printer configured on another operating system to use IPP. By default, the Printer Configuration
Tool browses the network for any shared IPP printers. (This option can be changed by selecting Action
=> Sharing from the pulldown menu.) Any networked IPP printer found via CUPS browsing appears
in the main window under the Browsed queues category.
If you have a firewall configured on the print server, it must be able to send and receive connections
on the incoming UDP port, 631. If you have a firewall configured on the client (the computer sending
the print request), it must be allowed to send and accept connections on port 631.
