I just bought an HP Officejet 4500 Wireless Printer but it never works when I try to print wirelessly. I can only print by connecting it to my laptop with a USB cable. It keeps saying:
Your computer is unable to communicate with your printer at (IP ADDRESS) This may be caused by firewall software. If you are using firewall software, verify that UDP port 427 is unblocked for both inbound and outbound traffic.
Your PC can not communicate with your printer at address (IP ADDRESS) Check all cable connections. Check that the printer, PC and router are powered on and connected to the network.
I've checked port 427 and it is unblocked for both inbound/outbound. I also tried the printer with my firewall off and it still didn't work. Someone help please?
I'm using Windows 7 and IE9. I also have Norton 360 installed on my laptop.
