Had to re-install HP4500 AIO printer after getting new wireless router. Not sure if it makes a difference, but am using WPA encryption now -- previously no encryption. Anyway, the printer software is installed on 2 laptops, one is Vista, the other (main computer) is Windows 7 x64. Using either one of these to send a 10-charracter Notepad document to the printer, it takes like 3 minutes for it to print out.
At one point during a test-print from the HP installation routine, I got a message about problems connecting with the printer and instructions to make sure the firewall was configured such that a certain port would allow the printer to work, but lost that window while I was trying to figure out how in the heck to see port settings and/or change them.
Appreciate any advice!
