Note: When using perforated paper, make sure that the printer does not
cut the paper at perforations or in an area that is 0 to 15 mm in
front of perforations (as viewed from the paper feed direction).
Otherwise, incorrect cutting may result. (See Figure 3.)
Note: When using perforated paper, be sure to prevent paper from being
caught, paper jams, paper from being cut during transport, and
other such problems. These problems may shorten the life of the
thermal head.
