And if you send this one:
<ESC> &a +40h
the print position will move right 40 decipoints and up 20 decipoints.
.4.4.11 Backspace
The Backspace control code works exactly as you might expect: it moves the print position one column to the left.
<BS>
Moving the print position back does not destroy any characters already sent. In fact, because of that, this command can be quite useful. It lets you superimpose one character over another.
Say you want to indicate a blank space as the letter b with a slash/ through it, an old programming symbol. Just send the b and then follow it with <BS> and the slash, and you get this: ~.
4.4.12Carriage return
The Carriage Return command by itself only moves the print position back to the left margin of the line on which it currently sits:
<CR>
If you want the print position to move down a line as well, send a separate Line Feed command each time, or use Define Automatic Line Ends (ex- plained below) to couple these two control codes.
4.4.13 Line feeds
The Line Feed command advances the print position one line down the page. The meaning of a line is set by the Line Depth command.
To send a line feed just send this control code:
<LF>
