I came across the same problem a while back.  My solution was to make a
background script called "Restore" that would show all the buttons that
were hidden by the printer button.

When the printer button was pressed, I showed the message box and put
Restore into it.  Then, if the user (who is really only me) ever hit
command period, I would see my buttons missing, see the message box with
restore in it, and remember that I just had to hit <return> to re-display
my buttons.  If the user didn't hit command-period, then the printer button
will call the Restore script after it finishes printing.

As long as the user is warned that he/she must hit return if something like
this happens, I'd say that this is an acceptable [:-(] solution to the
problem.

If anyone has better/other solutions, please let me know/post them here!
