Abstract: In order to provide a thermal printer capable of reliably performing an electric disconnection inspection for a heating element in the case of an optical identification code such as a bar code, reducing frequency of the electric disconnection inspection as necessary, and performing the electric disconnection inspection suitably for a use condition, a thermal printer includes: a platen roller that feeds a paper sheet; a thermal head having a plurality of heating elements for printing print data on a print area of the paper sheet fed by the platen roller; and a CPU that serves as an inspection unit that inspects whether or not there is an electric disconnection in the heating element and a control unit that controls operations of the inspection unit. The CPU is configured to change the inspection frequency.

Abstract: A printer using heat to print on a print medium improves a print processing speed over an entire print surface of a print medium. In print processing of a label (PL), the feeding speed at a print region (SW) for printing a barcode or the like is slower than a standard feeding speed, and the feeding speed at a margin region (SY) that has a length that is at least a predetermined length in the feeding direction (F) among the margin regions is faster than the standard feeding speed. Further, the feeding speed at a printing area (NW) for printing character, symbol, or the like, and the feeding speed at a margin region (NY) that has a length smaller than the predetermined length in the feeding direction (F) are set to the standard feeding speed. Accordingly, the print processing speed over the entire print surface of the label (PL) may be improved in the printer using heat to print on a label (PL).
