We are investigating having ATK print direct to Postscript, to relieve
the dependence on troff/groff and psdit.

I'm curious how many and what different Postscript interpreter versions
are being used out there.  Here we have one printer with interpreter
version 38.0, and another reports 52.3 (Here the version is reported on
the cover page, I'm not sure if that happens in general.)

The biggest issues are Level 2 operators, and ISO-Latin-1 support. 
Apparently ISO-Latin-1 support appeared in interpreter version 47.0.  In
versions prior to this there are 3 characters outright missing and a
number of others which would have to be constructed by composition of
other characters.

The following postscript code will print the interpreter version number
in the lower left corner.  If you use ATK printing (or would like to)
and you can, please print this on your printer(s) and let me know what
it says.

Thanks for any info,
