Short version: HP Envy 100 printer shows as available on IPad after restarting IPad or printer. About forty-five minutes later IPad cannot find printer. Latest version of firmware on printer, router, and latest update for IPad. Apple had me check Ipad at store on their printer, still working after one hour. HP sent me another printer, same problem. Set printer with static address, same problem. Change lots of settings on router, same problem. Does anyone have the same problem and more important does anyone have a solution?
