Roll media is wound on a core that can be 0.5 to 1.5 in. (12.7 to
38.1 mm) in diameter. Continuous roll media does not have gaps,
holes, notches, or black marks to indicate label separations. This
allows the image to be printed anywhere on the label. A cutter
can be used to cut apart individual labels. With continuous media,
use the transmissive (gap) sensor so the printer can detect when
the media runs out.
