Description

  The present invention relates to a label printer.

  According to Patent Document 1, because of the label pitch on the label mount, when a label that has been forwardly fed and finished printing is sent to the peeling position, a part of the unprinted label that is printed next is printed on the printing unit. After the printed label is peeled off, it is fed back until the leading edge of the next unprinted label exceeds the print position, and forward fed again to print on the unprinted label. A label printer having a backfeed mechanism for performing the above is disclosed.
