1. You've a wireless printer
2. A computer that has wireless connectivity.
If so, you're connecting the computer to a wireless network, for example "Belkinhome1" you need to connect your printer to the same Belkinhome1 and once your wireless printer and computer are on the same network.
Cool, now open the run command and type control printers and this will give you an option to open the printer menu. Now click on add a printer and your printer will be listed in the list of printers available for you to connect. Select the printer and go next and next and next until finish.
Everything is now set up, try to do a test print and things will and should go smooth from now on. Let me know if this has worked.
