Hi, working on a HP HP Photosmart C4740 All-in-One connected to a win 7 64 bit laptop. The laptop was very infected, I cleaned it thoroughly, it now runs fine, but her second issue was with the printer, no printing, no wireless. I uninstalled, reinstalled driver from hp site, configured the security etc, it connected to their network everything looked fine, no print. I tried via usb, still no print, everything looks fine, set as default, using virtual usb port. If I do a test print from the hp software its ok, but if I print from Office or Works, nothing, I see a flash of what may be the spooler, but then nothing, not a sound either. Spooler is set to auto and starting in services. Virus still? I ran killemall, nothing. I ran msft fixit, it found no issues, but windows printer troubleshooter could not identify the problem. Something else I noticed, trying to print from notepad I get a error "the handle is invalid" also there is evidence of repeated installs of the same printer on various ports, is there a way to clear these out? Ideas???
