Abstract
A thermal printer has a memory for storing printing patterns; a printer unit on which a thermal printing head having one line of dot print elements is replaceably mounted, the printer unit driving the printing head to print a printing pattern stored in the memory in a unit of one line; and a paper feed unit for feeding paper in a direction perpendicular to a direction of a print element line of the printing head. A first timer is provided for setting a print cycle for the printing head; and a second timer is provided for setting a feed cycle for feeding paper to the printing head at a selected speed. A controller concurrently drives the printer unit in the print cycle and the paper feed unit in the feed cycle, the controller driving the printer unit to cause the printing head to print in a print cycle while the paper feed unit is driven to continuously feed paper to the printer unit at the selected speed determined by the feed cycle set by the second timer. The controller adjusts at least one of the first and second timers to thereby adjust at least one of the print cycle and feed cycle, in such a manner that the length of the paper feed per printing line is equal to a print element pitch of the printing head.
