THE PRINT AREA

The maximum print area is 50 inches long. Most of your label application will fit into this area, therefore, it is
important to understand how to work with label that do not use the entire print area. The goal is to help you
avoid printing where no label exists, which may lead to print head damage, not to mention the frustration when
you cannot see the printed output.
The diagram below illustrates the print area for a sample 2 inch wide by 3 inch long label places within this area.
As can be seen, your label will be oriented against the inside left edge of the printer as viewed from the front
(label exit) of the printer. The normal reference point is located at the H1,V1 position of the print area in the
normal print orientation (no rotation).
