Patent ID: 7936365

Claim:
A printing method using a thermal print head (TPH), the method comprising: (a) printing an image on a medium using the TPH while feeding the medium in a longitudinal direction; (b) moving the TPH in a transverse direction by a predetermined value; and (c) printing an image on the medium using the TPH while feeding the medium in a longitudinal direction, wherein operation (c) comprises: calculating a transverse length of a region to be printed which remained on the medium and comparing the calculated transverse length with the transverse length of the TPH; printing an image on the medium using the entire portion of the TPH while moving the medium in the longitudinal direction if the calculated transverse length is larger than the transverse length of the TPH; and printing an image on the medium using only a partial portion of the TPH corresponding to the calculated transverse length while moving the medium in the longitudinal direction if the calculated transverse length is smaller than the transverse length of the TPH.
