We had a power outage for a couple of days. When the computer system came back up, the WIFI IP address of my Brother printer was changed to192.168.0.100. It had been all that but ending in 101.
I went to System Preferences and made the change. I even added the printer at the new IP address and deleted the printer at the old one. All that worked just fine.
But when I try to print, the printer icon that loads in the Dock has the OLD 101 IP address, and nothing I'm able to do will change that. I tried rebooting. I tried shutting down, unplugging, removing the battery, holding down the start button. Nothing worked. The only printer the print command will summon is the old one not found in system preferences but evidently stuck somewhere in OSX.
Ho do I flush out the old printer IP setting if it no longer exists in system preferences?
