Following the instruction on my printers website (Brother), it says to go to Devices and Printers and select Add a Printer. Going here I select Add a Printer then "The Printer that I want isn't listed". Then "Select a shared printer by name". and I get a list of the computers that are on my home network. So I choose the iMac that is the main one being that the printer is hardwired to it and also the wireless router.
But Windows asks me for a Network Password. So I try the password that I use for my Administer login but that does not work. I don't use another password that I know of. I try the network password which is different but that does not work either.
