Patent number: 8468392Abstract: A controller and a control method for a controller can simplify application development and can improve the performance of device control processes. When a request is received from an application 1 and the received process request is an initialization request, whether or not the received request is the first initialization request received after the application 1 started running is determined. If the received initialization request is the first initialization request, the request is passed to the device driver 3 and initialization settings information describing the configuration of the device driver 3 after the initialization process ends is stored. If an error has occurred in the device driver 3 when the device driver 3 status is detected, an error handling process is executed according to the device driver 3 state. When the device driver 3 has recovered, a request for setting the device driver 3 state to the state based on the initialization settings information is asserted.Type: GrantFiled: May 27, 2010Date of Patent: June 18, 2013Assignee: Seiko Epson CorporationInventors: Nobuhiko Nishimura, Toshihiro Hagiwara, Eiji Ito, Atsushi Sakai
