I currently own an HP Photosmart 5510 printer, which I've had for about four years. I'm no longer able to print, but the scanner still works. I think it has something to do with the compatibility with the print driver and the current OS. It bothers me that HP hasn't kept up with print drivers and now my printer is useless. I can't live without a printer, so I'm hoping some of you can suggest a good quality printer/scanner combination that works over a wifi network.
