Question: Can no longer see printer
I installed Mountain Lion on a partition so that I could continue to use my Canon Pixma MP600R printer and scanner. This arrangement has worked fine until the other day when the printer would not connect and was showing as unavailable. Nothing had been changed that may have caused this. I have tried reinstalling the printer drivers, re-adding the printer, and even reinstalling Mountain Lion. When I try to add the printer it simply does not show as being connected. Could it be the USB lead? I cannot try connecting with another lead as the printer end of it is a square connection. Thanks.
