I was given an HP PSC 1210 to use with my mid 2011 Mac Mini running Mountain Lion. I almost never need to print anything but I scan a lot (I save receipts, etc, that way). I plugged it in via usb, added it to my list of printers, and it said it can't find the software. See the attached pic. I downloaded the driver from the Mac Update site and it still tells me it has nothing. Any ideas?
