Chapter 7 Commands
Description
This command is used to move the reference point for the X- and Y-axes. All
horizontal and vertical measurements in other commands use the setting for R
as the origin for measurements.

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.
Warning!
Repeated printing off the edge of the label can cause excessive printhead wear.
Note that for narrow labels, the R command could be substituted by a q command,
which has the benefi t 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.
