The program works just the same as before, but the line spac- ings are just one-third what they were. This is because (ESC) “3” CHR$(n) sets the line spacing to n/216 inch.

Table 4-2 shows all the line spacing commands, including several “shortcut” commands for commonly used line spacings.

nMoving down the page without a carriage return

So far, all the commands that move the paper also move the print head back to the left margin. Normally this is what you want. Sometimes, though, you may wish to move down the page without moving the printhead back to the left margin. The following commands do just that.

The (ESC) “J” CHR$(n) command causes the printer to make one line feed of n/216 inch, but does not change the setting of the line spacing. Try this program to see how it works:
