I wrote a version of that for the Sharp PC1500 pocket computer years
ago. It was really simple on that machine -- you printed the text to the
LCD and then read the bitpatten back from the display (there was a BASIC
function to do that). Then just sent the bytes to the RS232 port, which i
connected to a punch.
