This option specifies the user-selected Label Length. In most applications,
the user-selected Label Length will match the physical label length. Physical
label length is the actual label length of the media installed:
Die-cut Labels: Measurable length of the removable label (leading edge to
trailing edge). This does not include the liner material or gap.
Tag Stock with notches or holes: Measurable length from the trailing edge of
one notch or hole to the leading edge of the next notch or hole.
Tag Stock with black marks on underside: Measurable length from the
leading edge of one black mark to the leading edge of the next black mark.
Continuous media (no label length indicators): Measurable length should be
within ± 1-2% the Label Length value here or the value sent via host software
command.
