I don't know this sort of problem happening really; but it's really suck since this virtual printer is so valuable.
If you do update this, you will suddenly find that you are not able to print anything to OneNote again and it's not just easy adding printer, and you will get it. :-P
Unfortunately, the solution is much easier--repair the program via add/remove programs.
- Control Panel >> Add/remove program (or Program and features in Vista)
- Choose Microsoft Office 2007, then click change
- Click next, next, ..., until it's done.
- after all, you have your OneNote printer back, easy?
:-P it's easy to fix; nonetheless, the truth is this shouldn't happen ever :-X
