the inherent mechanical value L
0
of the printer (shown as Figure 4), the calculation of tearing
position offset is shown as follows:
Tearing position offset=(L
0
+ distance of adjacent two black marks-L)/0.176 (dots number)
3. When the tearing position offset is not zero, or the distance Q between the beginning
print-position and the tearing position is greater than the inherent mechanical value Q
0
of the
printer (shown as Figure 5), the calculation of the beginning print-position offset of “GS ( F”
command is shown as follows:
Beginning print-position offset=(Q- Q
0
)/0.176+ tearing position offset
4. The inherent mechanical value of the printer: L
0
=A (mm) Q
0
=C (mm) (shown as Figure 1).
Examples for the black mark orientation control command of specified bill (Take D model as an
example):
The examples below assume that the paper tear position is on the printer tearing part, L
0
= 67mm,
Q
0
= 29mm (shown as Figure 1).
[Example 1] Bill requirement: Tearing position is on the preprint black mark position, and beginning
print-position of every bill is 32mm from the tearing position.

Note:
When the tearing position offset is being set, the parameter “a” of “GS ( F”
command should be “2”.
Note: When setting the beginning print-position offset, the parameter “a” of “GS ( F”
command should be “1”.
