Abstract
A printer and a process for correlating printed subject matter with subject matter that is meant to be printed by a printer with a printing mechanism or print engine such as a thermal printer including a print head, a platen, a media upon which labels are printed and a printer controller for imparting print data to the print head. An imager sends printed data as imaged to a read after print (RAP) controller for comparing the data received from the imager to data imparted to the print head or other printing mechanism. A tap, taps the data imparted from the print head and correlates it with the imaged data to determine the media speed, the image alignment, label analysis, weighing of blemishes, the gaps printed on a label, and other criteria.
