[comp.text] cminch and imagens

hartzell@boulder.Colorado.EDU (George Hartzell) (09/22/88)

I am having problems using the cminch font that comes on the Unix TeX
distribution.  It works fine using Beebe's dvijep program for the
laserjet-plus, but won't work on the imagen.  Beebe's imagen driver just
gives a blank page, while Chris Torek's (?) iptex program prints a mess
(it looks like some of the scan lines are vertically displaced by about
1.25 inches).  Is this something that I am going to have to live with, or
is it fixable?

Check the revision of the software on the Imagen itself.  Anything
older than about three years has some serious bugs in the rasterising
code.  More recent revisions have less serious bugs or no bugs (I had a
sample page, printed on, I think, rev 2.0) that mysteriously began
duplicating output lines about two-thirds of the way down the page,
with increasing density of duplication towards the end.  The last few
lines were almost solid black.  Printing the same file a second time
(after power cycling the Imagen, which had wedged) produced perfect
output.  One reliable way to crash old software was to define a glyph
with zero pixels (height=width=0, adv.width>0).

(Of course, it is possible that the latest software has some interesting
bugs too.  I think we are running version 2.6 of Imagen's software, but
this is from memory: the machines are at the University and I am at home.)

In article <13686@mimsy.UUCP> I wrote something thoroughly unreadable.
The essense of it was that cminch should print, and that the output
George Hartzell received implies a bug in the Imagen.

We are in fact running Imagen `System Version 3.3 Rev B IP/II'.
