ATM doesn't help *any* printer in that size range. The indifference point between having specific bitmaps versus letting ATM do its thing is right around 14 points. ==>Michael Costello costello@world.std.com ==>BCS*Mac, The Boston Computer Society Macintosh User Group ==>P.O. Box 2591; Woburn, MA 01888 617-631-8188 I think that statement is a bit misleading -- ATM won't help much when displaying 6-14 point text on-screen, and in fact, hand-tuned bitmaps will probably look significantly better. I can say from experience though that the printed quality of smaller sizes (I've only played with 9 point and up, but I suspect it applies equally well to smaller sizes) is noticeably better with ATM than without, even with 4x bitmaps installed. I would speculate that this is because the Deskwriter is a 300dpi printer, whereas bitmaps are 72 dpi, so a reduced 4x bitmap is really a 288 dpi bitmap represented in 300 dots per inch, where ATM will create a true 300 dpi bitmap. -- |- Peter E.
