Embodiment Construction

[0029] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. according to figure 1 The printing apparatus 100 of the first embodiment shown performs printing information on receipt sheets and journal sheets as printing media.

[0030] The printing device 100 includes an elongated housing 102, on one of its longitudinal end faces ( figure 1 An exit 104 is formed in the front of the middle), and the printed receipt is sent out from the exit 104. In the following description, the side where the exit 104 of the printing apparatus 100 is located is defined as the "front", and the opposite side is defined as the "rear". The housing 102 is formed by a lower housing 106 and an upper housing 108. The mechanism of the printing device 100 is provided in the lower housing 106, and the upper housing 108 is provided on the top of the lower housing 106. A front cover 116 is provided at the front of the upper ho...

Abstract

A first thermal head (132) is provided with at least one first heating element to perform printing on a first printing medium transported by first transporting means (134). A second thermal head (142) is provided with at least one second heating element to perform printing on a second printing medium (112) transported by second transporting means (144). A controller (200) controls the first thermal head (132) and the second thermal head (142) such that a first time period for which the first heating element is energized and a second time period for which the second heating element is energized do not overlap, while simultaneously driving a first motor (136) for driving the first transporting means and a second motor (146) for driving the second transporting means (144) at the same speed. <IMAGE>

Description

Technical field [0001] The present invention relates to a printing device designed to perform printing of multiple recording media at the same time, and to a method of controlling such a printing device. Background technique [0002] For the sales management of stores, point-of-sale (POS) stations have been widely adopted. A typical POS station includes a device that combines a personal computer, a display device, a drawer, a printing device, and a reader. One of the printing devices used in such POS stations has a receipt printing function for printing a receipt to a customer (purchaser), and a journal printing function for printing a journal of a copy of a store transaction (for example, in Japanese Patent Publication No. 9-234930A and No. 9-254496A). This printing device has two thermal print heads for printing data on a receipt sheet and a journal sheet. [0003] However, for this type of printing device, when two thermal print heads operate at the same time, the peak current...
