What is the use of a 400 dpi laser printer unless the screen |represents only a part of the printed page and you have some scrolling |mechanism? Maybe I haven't understood the fundamentals here. Can someone |illuminate me further on this matter. Much thanks. The article from BIX mentioned ~94 pix / inch. My guess is that they wanted 100, and the 94 was as close as was economically feasible. The printer is 400 dpi because you want high resolution on the printed page, so that it looks more like professionally prited stuff than like computer output. It does have a 300 dpi draft mode when speed or memory is more important than resolution. (If the imaging area were 8.5x11, which is isn't, the trade off is 14.96 million bits vs. 8.415 million bits, a considerable amount. If the difference means paging, the slowdown could be considerable.) (BTW, as to why I think they wanted 100 dpi on the monitor: converting 100 to 300 or 400 is considerable easier than converting 94.3 to 300 or 400. Maybe they even run the monitor as if it were 100 dpi rather than the 94+-.) -JimC -- batcomputer!cloos@cornell.UUCP |James H.
