Abstract
Image capture device control marks are automatically generated within a computer or printer and automatically printed on pages output from the printer. The control marks when detected by a control mark capable image capture device communicate information to the image capture device such as which areas of the printed page are text that require optical character recognition, which areas of the page are photos that require high-resolution full-color, which areas of the page are line drawings that require medium-resolution black and white, and which areas of the page are not to be scanned. Image capture device control marks may be configured in a wide range of sizes, styles, and locations on the printed page.
