OneNote is the default printer in the CS110 Lab (rm 231) right now.
If you go into start, printers and faxes and then see if Park_231 is in there. If it is, right click on the printer to set as default.
If Park_231 is not there, then click on the add printer button (top LH corner).
From there, it is a network printer, which means that you then have to go to the bryn mawr network (instead of searching the whole directory) then search for park_231.
Set as default printer.
This should solve the problem.
