I have a customer that has a 4 computer network. The main computer is Vista and the other 3 are 2 XP laptops and a Windows 7 laptop. The HP Officejet 6500 is installed to the Vista computer. and the other 3 computers are connecting wirelessly to the internet . The XP computers prints wirelessly but the Windows 7 computer will not print wirelessly. You have to take the laptop directly to the printer to get it to print. I have installed the Full software for Vista on the main computer and have installed the Windows 7 drivers and software on the Windows 7 computer but it will not print. It says it's printing but it goes off somewhere and never makes it to the printer. When you connect the laptop directly to the printer, it prints fine.
