I have an HP all-in on USB printer and nothing works with it except "cloud print " which required a seperate computer that the printer needs too be attached to. I wish HP, Epson, Kodax, etc. Would make android specific drivers that would allow us to directly connect USB printers and print to them with out the middle man (another PC ). It would make android tablets much more productive, My Samsung Tab 10.1 had drivers for all of Samsung printers so you could attach the Pinter via USB and pint normally. Now if only the other printer manufacturers would follow suit!(The developer who creates these drivers will make a fortune. Its a real need. Wish I knew how to create them but its not my area of expertise.
