Common, ordinary, everyday Microsoft Word works fine, at least on the
Macintosh. It's quite easy to make letters of arbitrary size for laser
printing, and it's not even terribly difficult to include things like
logos. I would bet most modern laser-aware word processors would do
it, although the Mac's WYSIWYG standard might make Mac processors a bit
easier to work with.
We often print in an outline font and fill in the letters in color by
hand (no color laser printer on campus) -- looks nifty!
