ABSTRACT:
A printing apparatus that enables transmission of information between its main body and a predetermined information processing apparatus includes first and second print media supplying sections, a paper feeding unit, first and second sensors, a storage section, a determining section and a communication section. The second print media supply section stacks print media of a different size from that of the first print media supplying section. The second print media supplying section is removably installed in the first print media supplying section. The paper feeding unit is commonly used for supplying the print media stacked on both the first and section print media supplying sections. The first sensor determines whether or not the second print media supplying section is installed and the second sensor determines whether or not the second print media supplying section can supply the print media. The storage section stores media information of the print media stacked in the first and second print supplying sections. The determining section determines the print media which can be supplied in accordance with outputs of the first and second sensors. The communication section transmits the media information to the information processing apparatus after having read the media information out of the storage section, the media information corresponding to the print media determined by the determining section.
