By the way, I added the source code in the NFO if you want to check how this thing is programmed :)

Some information: You switch the printer to "graphic" mode by sending the code 18, back to text with the code 17.

In graphic mode you use some prefixed commands to do things:
I -> Set the origin point
H -> Go back to the origin
Sn -> Set the character size (from 0 to 63)
Cn -> Set the color (from 0 to 3)
Ln -> Set the line type (from 0 for full to 15 for dashed)
M, D, R, J -> Used to move or draw in relative or absolute coordinates

The printer has a 0.2mm accuracy on 480 "pixels" in width on the paper, and all the move commands accept coordinates in the -999 to +999 range.

And yes it's slow as a snail, it needs to move the carriage to the left hand side to access the barrel selector gear to select the next color.

I did not really try to optimize pen movements, ideally one should do a short path computing algorithm starting with black, then switch to blue, then green and finally red :)

I think this is a bit too slow to be really interesting. Also, next time, you should probably make thicker lines, because it was really hard to see anything on the bigscreen. :-)

Doubling the lines would have make it twice as slow :)
