A while back, during a thunderstorm, one of our NeXT laser printers blew a
fuse, too.  It's too bad that the fuse is not accessable without having to
perform surgery.  

David's problem, however, may not be hardware related.  Yesterday, or maybe
it was the day before, two of our NeXTs forgot that they had printers.
Things were working just fine, then they just forgot.  Trying to print from
WriteNow would cause a PostScript PrinterDevice (or some such) error.  And
yes, the correct printer (the only printer) was chosen.  One of the NeXTs
magically started to see its printer again without any intervention, and the
other NeXT was brought back to reality by a reboot.  

Strange, eh?
