Printing system for printing on tabbed media

1. A printing system for printing on tabbed media having a plurality of tab positions, comprising:

a printing module for printing on sheets of tabbed media;

a front end for supplying image data to the printing module;

a media supply including a media tray adapted to be loaded with a plurality of sheets of tabbed media;

a media transport system configured to pick a next sheet of tabbed media from the media tray and direct it to the printing module;

a detection system configured to automatically detect the tab position of the picked sheet of tabbed media; and

a control system programmed to:

control the media transport system to pick the next sheet of tabbed media from the media tray;

control the detection system to detect the tab position for the sheet of tabbed media;

compare the detected tab position to an expected tab position and if the detected tab position is the same as the expected tab position instruct the front end to supply image data to be printed on the sheet of tabbed media having the expected tab position, and if the detected tab position is different from the expected tab position either:

instruct the front end to supply image data to be printed on the sheet of tabbed media having the detected tab position; or

control the media transport system 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, and instruct the front end to supply image data to be printed on the sheet of tabbed media having the expected tab position; and

control the printing module to print the supplied image data on the sheet of tabbed media.

2. The printing system of claim 1 , wherein the detection system includes:

an imaging system configured to capture an image of the sheet of tabbed media; and

an analysis system configured to analyze the captured image to detect the tab position.

3. The printing system of claim 2 , wherein the analysis system determines the detected tab position by detecting the tab in the captured image.

4. The printing system of claim 1 , wherein the detection system determines a sequence of tab positions for sequential sheets of tabbed media, and wherein if the determined sequence of tab position is reversed relative to an expected sequence of tab positions the front end is instructed to supply image data to be printed on the sheets of tabbed media having the reversed sequence of tab positions.

5. The printing system of claim 1 , wherein the detection system determines a sequence of tab positions for sequential sheets of tabbed media, and wherein if the determined sequence of tab position has a different number of tab positions relative to an expected sequence of tab positions the front end is instructed to supply image data to be printed on the sheets of tabbed media having the determined number of tab positions.

6. The printing system of claim 1 , wherein the detection system determines a sequence of tab positions for sequential sheets of tabbed media, and wherein if the determined sequence of tab position starts at a different first tab position relative to an expected first tab position 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 first tab position.

7. The printing system of claim 1 , wherein the control module is programmed to control the printing module to print labels onto tabs of the tabbed media.
