Hello, I have Canon MX300 printer connected to my Desktop Power Mac G4 MDD OS 10.5.8 and it never gave me any trouble printing from my computer. Just today when I was about to print out something, I got an error message says that the printer is off line. "Printing 'xxxxxxxxx' Printer is currently off line. Offline." The printer power is on and USB cable from computer to the printer is connected. I turned off the printer power off, disconnected the USB, then connected it back. Still having a problem. When I click on "HOLD" for printing job, the error message changes to "printer ready" When i click on "RESUME" it goes back to "Offline" please help.
