I am using imac snow leopard and the printer is connected by Ethernet. Problem is in the scan setting document size. Even f I select the letter size, it scans to legal and I have to physically go to each page and adjust the size. it faxes ok and prints ok, just the scan feature is a problem. I had the same problem before I upgraded from Leopard to snow leopard, but I was able to get a fix from HP to correct it, which did not work after the upgrade. The 1522 is a good printer but no longer supported by HP.
