I just found these two 'printers' in my printer folder along with my actual Canon i560.

Microsoft XPS Document Writer
Send To OneNote 2007

Using google I have determined that these are both part of Office 2007, which I do have.

But I have never seen these before, and have never had them as print options.

I'm assuming that microsoft update stuck them in, but I want to be sure.

Is that where they came from?? How do I tell??
