That could be an issue, if a print request was initiated and fulfilled
without the visitor's knowledge... it would be like how you can auto-dial a
fax number of have it run out of paper or toner.

In this case, though, we still see the system printing dialog... the
visitor to the site needs to grant permission for a document to print.

(It would be possible for an evil movie to continually throw up
print-request dialogs, true, but it would be simpler to freeze the browser
just by staying in a "while" loop for a month or so.)
