Therefore, I want to print specific size graphics at specific pixel locations on a printed page, using a program. The marks must be precisely in the right place so that the scanner can read them.

It is, if you keep the decimals, and don't change the font. The coordinates are calculated in the standard widths of the currently set font for the printer (as in Set Printer Font, qv in help).

I've just drawn a little graph on the screen, using character 'o' and calculating coordinates to row and column. Works great on screen - I can just assume it would do equally well on printer.
