where it touches the printed surface, or may not cut correctly. In this kind of situation, configure the amount of time

Roll Paper Settings

dialog box.

Alternatively, if the paper cannot be cut well by the cutter, set the

Automatic Cutting Settings

User Cut

Roll Paper Settings

dialog box, and cut the roll paper using scissors, etc.
