I purchased a used DV7 to replace my battered DV7 but I can't get the printer to print. Driver is installed and is reported to be working properly. On my old DV7, I kept getting additional HP2300 printers to install, so I would get a copy 1, copy 2 and copy 3 printers and would have to hit and miss on which one was the proper printer to use. I have tried removing all the drivers and even went into cmd.exe to delete any drivers (can't recall exacty what I was supposed to do), but I could not get into the authorization level needed. Also, all my USB plug ins seem to be working properly.
