I have just purchased an Acer Desktop and an HP all-in- one. The computer was pre-loaded with Windows 7. All attempts to install the printer, even by their tech support guy met with failure. The print driver does not load. However, it installs the scanner just fine. Several laptop users were able to hook up to the printer wirelessly on XP machines just fine. Trying to force the printer install from the basic driver get me to the point where it requests the port, but there are no ports showing. HP blames the computer setup. Acer did not supply me a setup disc. Has anyone solved a similar problem?
