"Hold For Authentication"

Because we're a bi-computer family, my husband has our printer set up on his new Windows 8.1 machine. I was able to network my MacBook running Mavericks and use the printer fine when he was using his Windows 7 machine, but even though I'm able to see the printer, every time I attempt to print the document, I get the "Hold For Authentication."

I've seen a few places online offer a workaround by saying use "guest/guest" as the username and password, but that doesn't work for me.

If anyone has any thoughts, they would be gratefully appreciated.

 

The thing is, I'm actually the one set up as the administrator for the Windows machine. And I still get the error. Let me try his and see what happens.

I don't hate on Windows, but it really shouldn't be this hard for it to talk to OSX.
