HP Photosmart 4750 wireless printer does not recognize my wireless network

[parearau]

Hello,
My printer worked fine with my computer (a wireless network) until I upgraded to Windows 7. Now after going through a reinstall (with the disk that came with my printer) I am still unable to print. Printer status still shows that print "job" went to printer and appears to be normal. I get no "will not print" or any other printer failure messages at all. What could be the problem?

Is the printer connected to the wireless network?
Is the PC?
Go to HP's website and download the printer drivers for win7 from them.
Is there any error messages on the printer? Got ink? (test print (built into printer) working ok?)

Edit: did you remove the old printer installation from devices and printers? Make the new one the default printer?
