Erik,

I cannot help with the data sheet, but in one of my former lives I did a
lot of embedded programming (using PIC and AVR) for a firm which uses
tons of thermal printers in their product.  This included producing the
fonts and pushing the bits out at the right time to a thermal printhead
as it went back and forth across the paper.  I might be able to help you
in that area.  That, by the way, was my first introduction to the AVR
back around early 1999 where Atmel-Norway converted my PIC assembly code
to C code for the AVR (for free) to gain a foothold.

Regards,
Don
