How can I share my wireless printer to other computers that are physically connected to the residentialgateway

Answer 1

If you know the IP address of the printer, you can add it as a IP printer. Go into the "Add Printer Wizard" and select "Local printer attached to this computer" and unchecked the "Automatically detect" box. Click "Next", the select the "Create a new port" and then in the drop down, go down to the "Standard TCP/IP Port", hit "Next", and "Next" again, then type in the IP address, you should be able to figure out the rest.

Answer 2

Do you have a wireless network for the wireless printer to connect to? Is that wireless network connected to the residential gateway?

You need to make sure the printer and computers are in the same windows network domain, default is "workgroup".

After that, add network printer using the printer setup wizard.
