Patent number: 9936087Abstract: 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.Type: GrantFiled: January 19, 2017Date of Patent: April 3, 2018Assignee: Seiko Epson CorporationInventors: Yuki Kuwahara, Tatsuo Akasaka
