If a network printer is inaccessible in a way such that dns doesn't fail and the connection isn't refused, system-config-printer hangs for several minutes while starting up or modifying that printer.
For example, if a laptop user has a printer ipp://192.168.1.123, but then tries to use the laptop on another network, system-config-printer will hang while starting up. Similarly, using something like ipp://example.com where example.com isn't actually reachable but does resolve can result in the same behaviour.
