The ImageWriter I printer requires a grounded, step-down, isolation transformer
when used with a 220V power source. Using the ImageWriter I printers on a
50Hz source can noticeably affect spacing between characters.
There are already several articles in the Tech Info Library that discuss the
ImageWriter II:
- "Part Available For Using ImageWriter II And ImageWriter LQ Overseas"
- "Electrical Specifications of Most Apple Hardware"
- "Using Apple Equipment Overseas"
