Actually, ESC/P has been pretty reliable for simple things like
changing font sizes, etc. But I haven't gotten to first base on
barcodes or even graphics code. I would also like to use some simple
graphics, like blacking-out something with a solid black square.

One thing I found out is that there is a 1998 ESC/P manual which has a
somewhat different escape sequence for barcodes than the 1997 manual
that I have. For example, the 1997 manual shows the length as 2 bytes
- an int and a mod. While the 1998 manual shows it as a "word". I
assume a "word" is 4 bytes in this case.

I'll try to track down the latest manual.
