Method for acquiring user identification information of destination apparatus under WSD protocol before sending read image data

摘要

In a push scan of a web services on devices (WSD) scan service, an information terminal apparatus performs a registration request to receive a service from a reading apparatus. A name of the information terminal apparatus is included in the registration request command, and a user can select the name of the information terminal apparatus as a destination of scan data when executing the push scan from the reading apparatus. However, at this point of time, a user name which is logging on the information terminal apparatus cannot be recognized. For this reason, a requisition command of an operation start request is issued to the information terminal apparatus on a network before the information terminal apparatus as a destination of image data is selected through a display unit of the reading apparatus. Therefore, a log-on user name extracted from a command including the log-on user name transmitted from the information terminal apparatus can be displayed on the display unit.
