StyleWriter II driver -- Dieder Bylsma wrote to tell us that he tried the head cleaning option from the StyleWriter II driver on his StyleWriter I, and although the printer itself seems OK, the process ruined the ink cartridge. This is probably why Apple isn't making the new StyleWriter II driver readily available and doesn't recommend that you use it with the StyleWriter I.
