My iMac doesn't detect the scanner function on my HP6500 ALL-IN-ONE WIRELESS PRINTER after upgrading from Leopard to Snow Leopard vers. 10.6.8 The HP 6500 prints
on command but both HP ScanPro & HP Device Manager give me the message:"that scanner could not be initialized, that scanner could not be found. I updated my IMac software which included some HP printer software. It apparently didn't help matters. Any suggestions?
