Abstract: A printing apparatus that includes a holding unit configured to hold a roll sheet performs supplying the sheet by rotating the roll sheet held by the holding unit; nipping and conveying the supplied sheet; performing printing on the conveyed sheet; detecting occurrence of a print medium jam of the sheet; and, if the printing apparatus has detected a print medium jam of the sheet, performing a control process of supplying the sheet in a state in which the conveying is stopped.

Abstract: There is provided with printing apparatus. A printing unit prints an image on a printing medium and is able to move. A cutter unit is able to connect with or separate from the printing unit, and, by following a movement of the printing unit, cuts the printing medium. A control unit, in a case where a predetermined condition is satisfied after the printing medium is cut by the cutter unit, causes the printing unit to perform printing on a succeeding printing medium, while moving the printing unit in a state in which the cutter unit is connected with the printing unit.

Abstract: A housing unit for containing electronic equipment consists of a plurality of housings which are connectable one to another. Each independent housing has respective first intake and exhaust ports formed in opposite sidewalls as well as respective second intake and exhaust ports formed in the front and rear walls respectively. An air flow passage is formed between the first intake and first exhaust ports through the chassis of the equipment contained in the housing when one housing is used as a stand alone unit. The individual housings are so constructed to be connectable in a way that air flow passages are conveniently formed in each housing with a common partition wall between the passages.
