I saw a Apple Silentype printer on Ebay, and I'm sort of interested in buying one but I wanted to ask if anyone has used one before, and if so... how does it compare to the ImageWriter I? I don't know anything about the Silentype printer. Is it a serial printer? Is it a thermal printer (thus silent?) I like the way it looks but I haven't decided if I "need" one or not. Thanks Ernest
