Abstract
A multihead thermal printer comprises a plurality of thermal heads arranged around a platen roller. An ink film associated with each thermal head includes an end mark leaving a length to an end of the ink film at least equal to that of one sheet of recording paper. A device for detecting the end mark is disposed adjacent to each thermal head. When the detecting device detects the end mark, the printer completes the printing of a sheet of recording paper in the process of printing, but stops the feed of a succeeding sheet.
