Have you experienced any problems--particularly with character spacing--
when using an Imagewriter I printer on a 50 Hz power source outside the US?  

-----

  In Apple's Tech Info Library article, "Using Apple Equipment Overseas" 
(dating from September 1988), it is stated that:

"The following devices require a grounded, stepdown, isolation transformer:
 - Daisy Wheel
 - Dot Matrix
 - Imagewriter
>>Using these printers on a 50 Hz source can noticeably affect spacing between
>>characters." (emphasis added)

  A faculty member here wants to use his ImageWriter I with a stepdown
transformer in West Germany.  He's read this article and is concerned
about possible problems he might have with character spacing.  However ...

  I've yet to see a report--either in _MacWorld_'s two articles on
'travelling outside the United States with your Mac' or the variety of
postings on international use of Macintoshes appearing in this
newsgroup--which describes a character spacing problem with the use of
the Imagewriter I with a 50 Hz power source.  The Apple Tech Info
Library article, "Apple Products Overseas," also does not mention this
problem.

  If you have used an Imagewriter I printer on a 50 Hz source with a
stepdown transformer, have you actually encountered character spacing
problems with the Imagewriter I on a 50 Hz source?  If you did, how
severe were they?  Did they affect draft mode (internal character set)
printing, better/faster printing, or both?

  Please send email; I will summarize to the net only if there is interest.

Many thanks!
