I print a small identification code on the bottom of forms to track not only the pc in use but also the program version:
@line,col say chr(27) + "x" + chr(0) // set draft mode
@line,col say chr(27) + "g" // sets 15 pitch
@line,col say your_string
Once the code has printed, I return to my original pitch with
@line,col say chr(27) + "M" // sets to 12 pitch
