Can't find Canon printer

My canon MP560 was set up perfectly, then I went to print and was getting a print paused problem. I reset my printers and now it's gone. when hitting the + to add the printer back, nothings happening. i reinstalled drivers to no avail. Any advice on how to re-add my wireless printer?
thanks

Go back to the Canon instructions. Completely remove the printer and drivers and then reinstall and set it up again. Let's see what happens. It sounds like your printer lost contact with the wireless network - which is why it disappeared. (Do not remove or uninstall the Canon wireless software or any other Canon software.) And keep a USB cable handy.

Also it would help if you told us how your wireless is set up. Are you using a router? Modem router? Network?
