[comp.text] TeX, Metafont, and 400 dpi NeXT printer

jesperse@wk18 (Dennis C. Jespersen) (02/25/89)

I've got TeX and Metafont running on a NeXT machine; the installation
was fairly easy, using the source files from ics.uci.edu (web sources and
web-to-C-ware) and labrea.stanford.edu (other TeX- and Metafont-ware).
I was interested in generating some 400 dpi fonts for the NeXT printer
(I had some 300 dpi fonts available which we use on an Apple LaserWriter.)
The Metafont parameters I came up with after some experimenting were:
blacker=0.75; fillin=0; o_correction=0;
(generating cmr10 at 300dpi with these parameters gave a font that matched
the "given" 300 dpi font pixel-for-pixel except for one character).
Then I tried cmr10 at 400dpi with these settings.  A comparison of the
font tables at 300 dpi and 400 dpi (from the "testfont.tex" file) shows the
400 dpi font is much improved over the 300 dpi font.  The quality of the
400 dpi font is really very good; the printer is impressive.

Generating a full set of Computer Modern and LaTeX fonts (93 fonts)
takes about 2.5 hours of processing time on the NeXT.  After packing to
pk format, the collection of pk files at magsteps 0,1,2,3 occupies
623, 753, 918, 1125 Kbytes respectively.

The dvi-to-PostScript driver I'm using is based on Beebe's dvialw; some
hacking was necessary to get it to produce correct 400 dpi output, as it
seems there are a few places in the code where the assumption is made that
the only possible output resolutions are 200, 240, or 300 dpi.

Good man.  It occurs to me that someone, or even NeXT, could save us all
a lot of wasted time by collecting the currently available font library
for TeX, doint the 400dpi and screen versions (90dpi? 100dpi?) and
...I know!  put it on a od cartridge and release it to the public domain!

You could always just scrap the Computer Modern fonts and use PostScript
fonts?  The NeXT machine uses the Display PostScript system, which
means you might not need tons of 400dpi bitmaps when you can use
outline fonts instead.

Perhaps this has already occurred to you and you have ruled it out for
other reasons, but I thought I should point it out, at least.

The availability of higher- and higher-resolution devices is one of the
main arguments against bitmap fonts.  Look at all the time, space, and
hassle they require so support a new printer (it looks like about 3
megabytes for a single font set).  Not to mention the differences
between write-white and write-black engines, etc., etc.

Or.....  Just tar it up and put it in one of the archives.
