There was a discussion on this newslist recently about how to put two logical tex/latex pages, reduced by 0.707, side-by-side on a single physical page. A few people posted PostScript hacks to to this. I tried `multipr' posted by Ross Cartlidge <rossc@extro.ucc.su.oz>. This works quite well, but there is a problem. dvips sends a bitmap 300dpi font to the LaserWriter, which is then reduced using appropriate PostScript operations. The result is in interpolated bitmap font, which doesn't look very good (some small letters are barely readable). Well, I happened to have at hand a set of 406dpi fonts (prepared for the Agfa 3400PS). I instructed dvips to use those instead of the normal 300dpi fonts, and shipped that to the laserwriter, along with the `multipr' commands. Much to my surprise, the result is almost perfect. I imagine the best results will be achieved by using a 424dpi bitmap (because 300/0.707 = 424.26). Anybody care to try? -- Marc Shapiro INRIA, B.P. 105, 78153 Rocquencourt Cedex, France.

Nope, the best results will be achieved by using a 212dpi bitmap
because 300 * 0.707 = 212.something
A 424dpi bitmap works reasonably well because scaling down a factor
of 2 isn't too hard. But metafont will still do a better job in generating
212dpi fonts than postscript will do in scaling a 424dpi font.

Actually, best results will be gotten with 212dpi fonts since 707 * 300 = 212.1. 424dpi will give decent results since we're dealing with an even multiple of pixels in the scaling. People dealing with nasty US paper will want to modify things so that the scaling ratio is 5.5/8.5 rather than .707 (The US ratio is .647 if you care). This calls for 194dpi fonts.
