Can you connect the printer directly to the router? If you can connect it, go open a web browser (Internet explorer, Mozilla Firefox, Opera) and enter 192.168.0.1 or 192.168.1.1 depending on your router of course, if they are both wrong then look it up. Once inside look for a place with a device table, it should have a list full of names of your devices and there IP addresses (example, Kitchen computer – 192.168.0.2, Living room computer 192.168.0.3) and look for one that says printer or the printers name and write down the IP address. Go to Control Panel and click Printer and Faxes, hit “Add a Printer”, select Local attached printer to this computer, uncheck automatically… Then on next page select, Create new port, and select on the drop list “Type of Port: Standard TCP/IP, a new window will pop up hit next, and where it says printer name or ip adress enter the IP address of your printer. Then let it ride through, once it asks you to print a test page print one, to see if it connected then attempt to print something. If it doesn’t work report back maybe someone else can help. Or look on the printers company website.
