Recently I posted a message on this newsgroup asking if anyone has "pk" files for cm fonts at 1270 d.p.i. I received several responses that these files are huge (someone told me 27M per font) and therefore could not be shipped across the net. In fact, my reason for asking for these pk files arose from my misunderstanding of how "dvi" files are printed on phototypesetters. I had assumed that the CM font bitmaps are downloaded to the phototypesetter within the postscript code, the same way that dvips/dvi2ps downloads the fonts for laserwriters. Actually, the usual way is to find a Linotronic 300 typesetter with the CM fonts already loaded. I found out that the American Math Society has such a typesetter, and that they can produce copy for a reasonable fee. This means that I don't need the pk files at 1270 d.p.i. Nonetheless, this raises some interesting questions in my mind; suppose I had a vanilla postscript typesetter, and I wanted to typeset a dvi file without downloading huge bitmap fonts. Two possible approaches would be: (a) Use only native postscript fonts. All the TeX math symbols would somehow have to be recoded into Adobe Symbol. Has anyone done this? (b) Download the CM fonts in outline rather than bitmap form. In this case, the size of the fonts files wouldn't change with resolution. Has anyone tried this? Thanks, Steve Vavasis

garbage, I am afraid. My entire pk1270 directory is 7 megabytes and
includes most of the CM family and a few others bits and bobs
dvips/dvi2ps downloads the fonts for laserwriters. Actually, the usual
way is to find a Linotronic 300 typesetter with the CM fonts
already
really? I haven't done it much, but I just a PostScript file with all
the fonts onboard and have experienced no problems.
(a) Use only native postscript fonts. All the TeX math symbols
would somehow have to be recoded into Adobe Symbol. Has

forget it, there are too many symbols missing. send the bitmaps of the
maths fonts - they are not that big
(b) Download the CM fonts in outline rather than bitmap form.
In this case, the size of the fonts files wouldn't change with
resolution. Has anyone tried this?
lots of people. it works. you can get the bitmaps in public domain or
for cash from Blue Sky. The former have difficulties, I understand.
The problem is that the outline fonts are also huge! if you are
looking into saving transmission time or disk space, it don't signify
much (IMHO)
