r – Set Relative Reference Point
Description
This command is used to move the reference point for the
X- and Y-axes, relative to the label width set by a previous
q
command.
Syntax
rp
1
,p
2
Parameters
p
1
Horizontal (left) margin measured in dots (default 000).
p
2
Vertical (top) margin measured in dots (default 000).
Remarks
The relative reference point command is used to establish the top
and left margins relative to the label width.
For narrow labels, the
r
command can be used after a
q
com-
mand, which has the benefit of making better use of a limited
image buffer. The values for the latest
r
command (or
R
, which-
ever was last executed) are printed on the test label.
The print direction commands
ZB
and
ZT
affect the location of
the relative reference point, as illustrated below:
Example
r50,100
↵
:
Creates a 50 dot left margin and a 100
dot top margin from label edge set by q command.
Maximum Print Width
Label width set by q command
