die-cut or not ched.
Notched media:
notch must be 1/4 inch wide x 3/32 inch
long located on the left side of the label as viewed from the
front of the printer.
Black-mark media:
marks must be located w ithin 1 mm o f
the left edge of the media as viewed from the front of the
printer;
Mark thickness: 0.12 - 0.43 inches (3 mm - 11 mm);
Mark width: 0.43 inches (11 mm) - full media width; mark-
to-mark leading edge registration tolerance ±0.016 inch (± 0.4
mm);
Mark density >1.0 ODU (Optical Density Unit);
Ma ximum density of th e back of the media on wh ich the
black mark is printed: 0.5 ODU.
