Not sure if it will help you or not but I finally got things working, at least for now.
First thing I did was go to Control Panel - Network and sharing Center. From there I clicked the "Change Advanced Sharing" option on the left. At that screen if you go down a bit there is an option for "Password protected sharing" and you have 2 choices, to either turn it on or off. I turned it off.
Then I went to notepad and opened a txt file and told it to print. In the screen that opens where you select the printer, if it isnt already showing as an option then select "Find Printer". Then it will locate the networked printer. If it gives you a message about needing a
driver then go to the web site for your printer and download the right
driver. Install it and Viola!!!
This at least worked for me, hope it helps you too.
