Paper cutting/tearing position offset = (L0 + length of two neighbor black mark
－
L)/0.176 dots
Note:
When setting the paper cutting/tearing position offset,
parameter
a
of
GS ( F
is 2. (a = 2)
3. When paper cutting/tearing position offset is not 0 or the length (Q) of print starting
position is larger than the printer inherency mechanism value (Q0), offset set by
GS
（
F
is calculated as follows:
Print starting position offset = (Q-Q0)/0.176+ paper cutting/tearing position offset
Note:
When setting the paper cutting/tearing position offset,
parameter
a
of
GS ( F
is 2. (a = 1)
4. Inherence mechanism value of mechanism DP330:
L0=43mm, Q0=18mm
When the mechanism is installed in the printer enclosure, values of L0 and Q0 will
change, that is,
L0=43+
Δ
L, Q0=18+
Δ
L
5.
Δ
L calculation method:
1) Load the paper first, and trim the paper edge;
2) Send 20 characters “E” to the printer and print these out;
3) Feed the paper to proper position, and measure the length within the paper end
and the top of “EEEEEEEEEEEEEEEEEEEE”, which minus 18ms equals
Δ
L.
Examples for the black mark position control for specified paper.
The paper tearing position assumed to be the printer cutter position, that is L0=43mm and
Q0=18mm
【
Example 1
】
Paper: Cutting/tearing position is on the printed black mark position, which is
25mm distance away from the print starting position.
