Provided is a technique for allowing a user to easily check the status of an image scanning apparatus. An image scanning apparatus is configured to transmit original document image data by storing, sequentially in a buffer, line data obtained by line-by-line scanning of an original document and transmitting the stored line data to a host computer sequentially line by line, and includes a control unit configured to perform control to transmit original document image data including notification image data to the host computer in a case where it is detected that the apparatus status of the image scanning apparatus is not normal during processing executed in response to a scan command received from the host computer, the notification image data being a notification of an error occurrence.

A method and system of controlling at least one printbar in a printing system are described. The printing system has one or more of printbars distributed along a media transport. A first image including a reference pattern is generated on a print medium with a first printbar. A pattern is then detected on the print medium. The reference pattern and the detected pattern are used to determine a position of the first image relative to a second printbar. This position is used to configure nozzle data for a second image to be generated on the print medium by the second printbar.

A method and system of controlling at least one printbar in a printing system are described. The printing system has one or more of printbars (160, 190) distributed along a media transport. A first image including a reference pattern (240A, 240B) is generated on a print medium (150) with a first printbar (160). A detector (180) then detects a pattern on the print medium. The reference pattern and the detected pattern are used to determine a position of the first image relative to a second printbar (190). This position is used to configure nozzle data for a second image to be generated on the print medium by the second printbar.
