Abstract: A printing system for printing on tabbed media having a plurality of tab positions. A media transport system picks the next sheet of tabbed media from a media tray. A detection system detects the tab position for the sheet of tabbed media. The detected tab position is compared to an expected tab position and if the detected tab position is different from the expected tab position then either the front end is used to supply image data to be printed on the sheet of tabbed media having the detected tab position, or the media transport system is controlled to direct the sheet of tabbed media into a waste receptacle and pick one or more additional sheets of tabbed media until the detected tab position is the same as the expected tab position.
