http://ubuntuforums.org – I Installed 12.04 in July, worked with the office printer perfectly. tried to print today and it wont. in the printer settings dialog it says: Quote: printing service not available. Start the service on this computer or connect to another server so i attempted to start cups and got: Code: $: service cups start start: Rejected send message, 1 matched rules; type="method_call", sender=":1.153" (uid=1000 pid=17105 comm="start cups ") interface="com.ubuntu.Upstart0_6.Job" member="Start" err (Hardware)
