Printer error HallWAy first imac

First IMac in the hallway the printer is not working

I fixed this issue this morning by uninstalling and reinstalling the printer xerox7760@macserver.local.
SystemPreferences>Print & Fax > click the minus sign to delete the printer, then the plus sign to add a printer, select it from the list, and add it. Then click the padlock icon to lock the preference, make a test print, and log out.
