Label Design
Origin
The positioning of all printable objects on the label uses a
common system. The starting point (called the origin) is the
point on the media that corresponds to the innermost active dot
on the printhead at the moment when printing is started. The
location of the origin is affected by the following factors:
• Position across the media path (X-axis):
The position of the origin in the X-axis is determined by the
Xstart value in Setup Mode.
• Position along the media path (Y-axis):
The position of the origin in the Y-axis is determined
by the Startadj and Stopadj values in Setup Mode and by any
FORMFEED
command executed before the current
PRINT-
FEED
command or after the preceding
PRINTFEED
.
Coordinates
Starting from the origin, the X-axis runs across the media path
from the center section and outwards and the Y-axis runs along
the media path from the printhead and back towards the media
supply.
Units of Measurement
The unit of measurement is always “dots”, that is, all measures
depend on the density of the printhead. The EasyCoder E4 has
an 8 dots/mm printhead where a dot is 0.125 mm = 0.00492 in.
Insertion Point
The insertion point of any printable object is specifi ed within the
coordinate system using
PRPOS
|
PP
. The coordinates must be
selected so the fi eld fi ts entirely inside the printable area.
PRPOS

PP
<x-coordinate>,<y-coordinate>
<x-coordinate>
the distance in dots along the x-axis from the
origin to the insertion point
<y-coordinate>
the distance in dots along the y-axis from the
origin to the insertion point
Default value:
