You should be all set. Select the printer name that includes
the code as part of the name, as listed above.

Your computer may create a duplicate printer without the code
included in its name. That one probably won't work.

Also your printer may ask for your username and password the
first time. Use your UMass netid and the account code as the 
password, though I'm not sure this prompt actually does anything, 
hence the need to provide the code during this setup process.

You probably need to reboot and/or restart your individual 
applications before they work completely.

Press Ctrl-D or type "exit" to close this terminal window.
