  • Patent number: 9936087
    Abstract: A printing apparatus includes a printing unit that performs a printing operation, a print setting unit that performs setting of the printing operation, and a touch panel that displays an object related to the setting and receives a pressing operation. The touch panel displays operation objects corresponding to a multi-level changeable operation parameter of the printing operation and when the pressing operation is performed on a position where the operation object is displayed, the touch panel changes a temporary setting value of the operation parameter, which is shown by a display object displayed at a position different from that of the operation object, according to a magnitude of pressing force. The print setting unit decides the temporary setting value, which is obtained when a determination operation different from the pressing operation is performed, as a setting value of the operation parameter.

  • Patent number: 9849686
    Abstract: The invention relates to a method of charging for ink in an ink container consumed by a printing unit during printing. The method of charging includes obtaining information on an amount of the ink consumed; and implementing charging on the basis of the information. Before the amount of the ink in the ink container consumed reaches a predetermined value, first charging is implemented according to a charging basis in which usage-based charging is implemented on the basis of the amount of the ink consumed. After the amount of the ink consumed reaches the predetermined value, second charging is implemented according to a charging basis different from the charging basis applied to the first charging.

  • Patent number: 8384950
    Abstract: When color measurement is performed, a printer driver of a host apparatus 150 transmits a job start command “JS” to a printer 10, then performs printing instruction (print data transmission for color measurement printing), color measurement instruction, reception of a color measurement result (color measurement data) from a color measuring device (a color meter 41 and a color measurement driving device 80), label printing instruction, job information storage instruction, and positioning instruction, and subsequently transmits a job end command “JE” to the printer 10. During a period from the job start command “JS” until the job end command “JE” is received, a communication connect between the printer 10 and the host apparatus 150 is maintained while an interrupt from other than the host apparatus 150 is inhibited.
