Same here, updated three laptops to Ubuntu 120.4 LTS. Printing works fine as long as I am connected to the network via (LAN) cable. The moment it pull the cable and switch to WLAN I get the message "unable to locate printer". (All other functions work when connected via WLAN: so I have mail in Thunderbird , can browse the internet with Firefox and sync my stuff with UbuntuOne. It is just the printing which does not work over WLAN.)
Additionally, I cannot find/locate/add any new printer when connected to the WLAN. But I see both network printers (in my home-network) when connected via LAN. Seems that CUPS and/or Avahi have a big problem with WiFi at the moment. (I can see and find printers when using connecting my Mac over WiFi, so the problem does not originate from the printers ). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/987212 Title: Wireless printer "Processing - Unable to locate printer."
