PIXMA MG7720 -- printer in use


I'm trying to print from my laptop over a wireless connection. The print queue states I cannot print because the printer is in use by another computer. No other computers are currently on or in use. I deleted all print jobs in the queue, but I still get the same message. Ideas?
