PRINTFEED Statement
Also see:
• Chapter 11.3
Origin
The positioning of all printable objects on the label, i.e. text fields,
bar code fields, images, boxes, and lines, uses a common system.
The starting point is called “origin” and is the point on the paper that
corresponds to the innermost active dot on the printhead at the
moment when the PRINTFEED statement is executed.
The location of the origin is affected by the following factors:
• Position across the paper web (X-axis):
The position of the origin is determined by the X-Start value in the
Setup Mode.
• Position along the paper web (Y-axis):
The position of the origin is determined by the Feed adjustment
in the Setup Mode and any FORMFEED<nexp> statements
executed before the current PRINTFEED statement or after the
preceding PRINTFEED statement.
Coordinates
Starting from origin, there is a coordinate system where the X-axis
runs across the paper web from left to right (as seen when facing the
printer) and the Y-axis runs along the paper web from the printhead
and towards the rear end of the paper.
Units of Measure
The unit of measure is always “dots”, i.e. all measures depend on
the density of the printhead. For example, in a printer with an 8 dots/
mm printhead, a dot is
1
/8 mm = 0.125 mm = 0.00492" or 4.92 mils.
This implies that a certain label, originally designed for 8 dots/mm,
will be printed smaller in an 11.81 dots/mm printer and larger in a
6 dots/mm printer.
Generally, a dot has the same size along both the X-axis and the Y-
axis. An exception is 11.81 dots/mm printers, where – for technical
reasons – there is a very small difference (see Technical Manual).
Insertion Point
The insertion point of any printable object is specified within this
coordinate system by means of a PRPOS<x-pos>,<y-pos> state-
ment. For example, “PRPOS 100, 200” means that the object will
be inserted at a position 100 dots to the right of the origin and 200
dots further back along the paper.
