All types of media should normally be wound with the printable side facing outwards and unroll from
the top of the roll.
However tags and continuous strip can optionally be wound with the printable sidefacing inwards and
unroll from the bottom of the roll as long as they are not used for cut-off operation.
Protect the media against sand, grit, and other hard particles during printing and storage.
Keep the cover closed. Even very small foreign particles may cause severe harm to the
delicate printhead.
