R – Set Reference Point
Description
This command is used to move the reference point for the X- and
Y-axes. All horizontal and vertical measurements in other com-
mands use the setting for R as the origin for measurements.
Syntax
Rp

Parameters
p
1
Horizontal (left) margin measured in dots (default 000).
p
2
Vertical (top) margin measured in dots (default 000).
Remarks
The reference point command is used to establish top and left
margins to prevent printing off the edge of the label. A minimum
margin of 1 mm should be used on all sides of the label.
Repeated printing outside the edge of the media can cause
excessive printhead wear.
For narrow labels, the
R
command could be substituted by a
q
command, which has the benefit of making better use of a
limited image buffer. However, the
q
command cannot affect the
vertical margin. Any
R
command after a
q
command will revoke
the latter.
The print direction commands
ZB
and
ZT
affect the location of
the reference point, as illustrated below:
Example
R50,100
↵
:
Creates a 50 dot left margin
and a 100 dot top margin.
