my friend just bought a brand spankin new compaq(p4 1.5 ghz, 512ram, blah blah,,) installed with XP Home Ed. and a brand new HP spc 750. the printer uses a USB cord to connect. And when i put it all together it reconizes that its a 750 then it pops up a screen saying driver invalid... i looked alll over the HP website and all it did was spin me in circles til i went crazy!! i tried using the CD and it installed and everything , the only problem is that it says something about corrupt files... and when i do get it installed i try to print out a test page and it tells me to add a printer. i try to add the 750 then everything starts all over again~! wat do i have to downlaod? wat do i have to change? and if u could send me a link..
