1. The next horizontal position is set.
2. Description of the parameters:
P
no
is the amount of data according to P
no
(MSB is invalid):
06H is the default.
The command is invalid, if P
no
< 06H.
A
1
determines the type of printing position:
A
1
odd = relative printing position from current position.
A
1
even = absolute printing position from left margin.
A
2
determines the direction of the relative positioning:
A
2
odd = backwards
A
2
even = forward
A
2
is invalid, if A
1
is even-numbered.
P
1
... P
4
Set printing position:
Low-order half byte is valid (0 ... 9)
High-order half byte is invalid.
The absolute/relative printing position is calculated as follows:
P
1
* 1000 + P
2
* 100 + P
3
* 10 + P
4
* 1
The unit for positioning is as follows:
LQ 1/360 inch
UTL 1/240 inch
If the bar code is positioned so that it extends beyond the right mar-
gin, printing is suppressed. If the positioning extends the bar code
beyond the right margin, a »CR/LF« (Carriage Return/Line Feed)
is performed.
