Some time ago, I posted a message about some of the characters from some fonts
in the LaserWriter II being different from ones in the LaserWriter+. I have
since tracked the problem down to the "1" from NewCenturySchlbk-Bold, which has
been changed so that it has the same width as the other digits. There may be
other fonts which are different, but I have not noticed them.
Since I got no feed-back from my last message, I don't know whether anyone else
has noticed this problem, or cares :-), but I will describe the solutions I have
found anyway.
Since my problem was with TeX output, the first solution (suggested by
ArborText) was to convert the TFM (TeX Font Metric) file to ascii form using
tftopl and modify the width of the 1 and then convert this back using pltotf.
This works but it means that if you want to print DVIPS output on both LW+'s and
LW II's then you are stuck.
A better solution we found was to modify the font in the LaserWriter II. Here
is the PostScript we send to the printer which makes this change permanently
(until the LaserWriter is turned off).
