I got my wife on the 'net, and with a talk session going in on window and
a shell in another, I sent files to the printer and had her interpret the
results.

I used the Graphic2.prn file, and used beav to modify the file before
sending it to the printer.  First we printed the original file unmodified.
Then I removed the ESC(D command entirely, then I changed 78 28 to 28 50,
then I sent the command with all four bytes 0, and finally we printed the
original again, to guage changes in the printer itself due to warming up.

The result was that all the images seemed to be identical, within the
variation of the two prints of the original.

That's all that time would allow.

I have to run.  I have to shlep back across the country tomorrow.  Luckily
it's a rather narrow country.
