So, I decided I wanted to be able to print stuff from my iMac and have it print in my parents room because I don't have a printer. I have a Mac, my mom has an IBM. I go to "Printer Setup Utility" > "Windows Printing" >Network Neighborhood" > MSHOME. so then I get "IBM" so I choose it and I have to enter a username and password. So I enter "Viky" "•••••" which are correct and then I get this... So obviously it's not working. Am I doing something wrong?
