Have a new Macbook Air 13 with El Capitan and an old HP 6520 Photosmart Printer. Tried to print a photo with the Mac today for the first time, and could not figure out how to select the printer tray. Finally discovered that probably I need the appropriate printer driver, so I downloaded one from HP (first time for that, too) which was up through a couple OS releases ago. Still can't find where to locate the printer tray selection. Don't really want to call HP because (1) service agreement has expired and (2) I managed to burn my bridges with them over why the service agreement expired. Would appreciate some input on what I might do. It also comes to me that I might be shopping for a new printer. Would like suggests on one that is good for home use, photos, can copy and does scans. And, obviously, one for a Mac. Epson WorkForce?
