  • Publication number: 20210026577
    Abstract: Disclosed are a printing method using websocket communication and a management method for a websocket communication channel. The printing method includes establishing, by a printing apparatus, a websocket channel for communicating with an external apparatus, requesting, by the printing apparatus, print data from the external apparatus through the websocket channel, determining, by the printing apparatus, whether a predetermined condition associated with an acquisition of the print data is satisfied in response to the request for the print data, and controlling, by the printing apparatus, a channel duration time of the websocket channel when the predetermined condition is satisfied.

  • Publication number: 20200236242
    Abstract: A printing apparatus supporting USB type-C includes: a USB type-C interface configured to support a connection with an external device; a printing unit configured to perform printing; and a controller configured to control the supply of power to the external device. The controller checks a reception power received from an external power source, predicts the estimated power consumption of at least one of the printing apparatus and the external device, determines a supply power to be transmitted to the external device based on the reception power and the estimated power consumption, and transmits the supply power to the external device via the USB type-C interface.

  • Publication number: 20130262236
    Abstract: A point-of-sale (POS) system is based on a portable computer. The POS system includes a main processor to which a host central processing unit (CPU) and a software graphics application program interface (API) are mounted; a memory interface to which a memory chipset and a bus-to-device component are mounted; a graphics system to which a graphics accelerator, a Rambus arbiter peripheral component interconnect (PCI), a direct memory access (MA), a random access memory digital-to-analog converter (RAMDAC), a queue and a block write are mounted; an internal monitor as a first monitor; a wireless module, which wirelessly transmits graphics data; and an external monitor, which displays graphics data that is received wirelessly or via wires from a portable computer. The portable computer supports the external monitor with a copy mode, an expansion mode, and an extension mode.
