Photosmart D7460 v- HP You have Software Problems

The is a great color printer for documents and photos...when it works. I found serious communication and disconnect problems with the HP software in wireless mode. These problems persisted on three different home computers and two operating systems, Windows XP and Vista. I am spending more time reloading HP driver software and printing "Test Pages" than I am doing serious computer and photo printing. I have a wireless network and CA security software. Maybe these are the issues with HP's wireless printer mode, but no matter I think it is HP's responsibility to write software that is user friendly, which this is not in wireless mode. I have recently switched the printer to the USB wire mode and the the software communication problems that I experienced in wireless mode disappeared. Also, the HP wireless software affects Windows XP when when the computer is in shut down mode. Instead of shutting the computer down automatically, Windows does not seem to know what to do to end the HP Photosmart software. I have to manually "End Program (I/O device error)" to shut my computer down.
