Using these commands you can position text or graphics exactly on
a page. (Vertical positioning can also be achieved by variable line
feed and by line spacing commands). With the variables n
1
and n
2
in
both commands a specific dot position can be defined at which the
printout is to start. The variable values are ascertained as follows:
n
2
= integer value (dot position/256)
n
1
= dot position - (n
2
* 256)
The command ESC $ uses the default or set left margin as reference
point and moves the respective print position in 1/60 inch steps.
For a narrow printer the maximum number of dots per (8 inches) is
480, for a wide model (13.6 inches) it is 816 dots. With absolute posi-
tioning of 5 inches (300/60) from the left margin the calculation of
the parameters looks as follows:
