I have a shared printer on my home WiFi network, and once in awhile it disappears from the shared section of finder. I check the printer and it is in fact still connected to the network, it just can't be seen by my mac. A reboot fixes this, but is there a way to reset the shared section of finder so that it refreshes, in other words goes out to find whats on the network? Maybe via command line? Rebooting is annoying. Thanks in advance.
