Description
This code sequence moves the print head to a relative print position without regard to the
current character density. This print position is calculated according to the formula
(n
1
+ 256
∗
n
2
).Each dot, i. e. each print position has a width of
1
⁄
120
inch in DPQ and
1
⁄
180
inch in NLQ and LQ.
Calculation of the values of n
1
and n
2
first requires the prefix (n dots) to be calculated. If
the movement is directed towards the left side, the result is subtracted from 65536. Sub-
sequently the values for n
1
and n
2
can be calculated according to the formula:
n
1
= n MOD 256
n
2
= INT(
n
⁄
256
)
If the print position exceeds the currently set margins after execution of the horizontal
step, this code sequence is ignored.
This code sequence can be used in all print qualities (DPQ, NLQ, LQ).
Example for calculating n
1
and n
2
:
Movement of 4 inches towards the right side:
n= 4
*
120
= 480
n
2
= INT (
480
⁄
256
)
= dec.1
= hex.01
