Windows Credentials Prevents Adding of Printer

If you ever encounter a problem where one computer (Let's call it computer A) cannot see the printer hooked up to another computer (Let's call it computer B) in your wireless home network, you might want to check if Computer A has existing windows credentials associated with Computer B. The credentials basically allow Computer A to log on to Computer B. So if the credentials have a wrong username or password, say a blank password, then Computer B will prevent Computer A from logging on and using any resources attached to it (In this case, the printer attached to computer B). Check out and study up on Windows Credentials Manager.

So to solve the problem, all I had to do was delete any existing credentials associated with Computer B that were stored on Computer A. Then, I tried adding the printer once more, this time, making sure I had the right username and password for logging on to Computer B. Afterwards, the printer could now be seen by Computer A. Printed out a test page to ensure that everything was working properly.
