Problems solved by technology

However, the pressing of the nip roller is nothing more than resistance to the pressure roller.
Therefore, if the nip roller presses the pressure roller too strongly, it will cause a reduction in the printing speed caused by a reduction in the label paper conveying speed.
Especially for battery-driven portable printers, the conveying speed of label paper is likely to decrease significantly due to the limitation of power supply capacity.
If the machine is thus set up to accommodate the occasional exceptional label stock with strong label-to-backing adhesion, it will result in the disadvantage of reduced printing speed when using other standard label stock, which predominates. very inconvenient

Embodiment Construction

[0019] Embodiments will be described with reference to the drawings.

[0020] figure 1 is a perspective view of the portable printer 101 . The portable printer 101 of this embodiment is powered by the slave battery BT (refer to figure 2 and image 3 ) to supply electric drive. The portable printer 101 performs printing on roll paper P as paper based on the stored printing data. As the roll paper P, label paper 203 wound in a roll can be used (see figure 2 ), invoice paper wound in rolls or non-release label paper wound in rolls (not shown in the figure). The label sheet 203 has a backing sheet 201 and a plurality of labels 202 attached to the backing sheet 201 . In addition, in the case of using the label paper 203 as the roll paper P, the portable printer 101 can implement either the separated output in which the label 202 is separated and output from the backing paper 201 or the continuous output in which the label 202 is not separated from the backing paper 202. ou...
