Embodiment Construction

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

[0030] The printing device 100 includes an elongated housing 102, at one longitudinal end thereof ( figure 1 An outlet 104 is formed in the front of ), and the printed receipt is sent out from the outlet 104. In the following description, the side where the outlet 104 of the printing apparatus 100 is located is defined as "front", and the opposite side is defined as "rear". The housing 102 is formed of a lower housing 106 in which the mechanism of the printing apparatus 100 itself is disposed and an upper housing 108 disposed on top of the lower housing 106 . A front cover 116 is arranged at the front of the upper casing 108, and the front cover 116 can be opened and clos...

Abstract

A printing device, wherein a first thermal head is provided with at least one first heating element to perform printing on a first printing medium transported by first transporting means. A second thermal head is provided with at least one second heating element to perform printing on a second printing medium transported by second transporting means. A controller controls the first thermal head and the second thermal head 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 for driving the first transporting means and a second motor for driving the second transporting means at the same speed.

Description

technical field [0001] The present invention relates to a printing apparatus designed to simultaneously perform printing on a plurality of recording media, and to a method of controlling such a printing apparatus. Background technique [0002] For sales management of stores, point-of-sale (POS) stations have been widely adopted. A typical POS station includes a unit incorporating a personal computer, display unit, drawer, printing unit and reader. One of the printing devices used in such POS stations has a receipt printing function for printing receipts to customers (purchasers), and a journal printing function for printing journals for copies of store transactions (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 receipt sheets and journal sheets. [0003] However, with this type of printing device, when two thermal print heads operate simultaneously, the peak current is hi...
