[Function] 
Based on the current position, sets the print starting position through
calculation using the basic calculation pitch. 
A positive number specifies the print starting position to the right of
the current position; a negative number to the left.
Negative numbers are specified using the supplement of N. 
The print starting position is determined through the following calcula-
tion. 
To the right 
n1 + n2 
×
 256 = N
Example 
1 dot to the right:
n1=1, n2=0 
2 dots to the right:
n1=2, n2=0 
3 dots to the right:
n1=3, n2=0 
        :
576 dots to the right: n1=64, n2=2 
        :
To the left 
n1 + n2 
×
 256 = 65536 – N 
Example
1 dot to the left:
n1=255, n2=255 
2 dots to the left:
n1=254, n2=255 
3 dots to the left:
n1=253, n2=255 
        :
360 dots to the left: n1=192, n2=253 
        :
The distance between the print starting position and the beginning of
the line is as follows. 
×
 (basic calculation pitch) 
[Notes]
Any specification that exceeds the end of the line is ignored.
This calculation is made based on the basic pitch in the horizontal
direction.
In case of overlapping with the print data expanded currently, over-
printing is performed.

[Function] 
Selects which paper-end detector causes the printer to stop printing. 
When printing is stopped, the line being printed is completed. 
Even if printing stop is invalid, the printer stops printing and the print
data is discarded when the paper is out.
