Abstract
Method for determining enhanced printing functions on a hand-held inkjet printer having one or more optical sensors configured to measure speed and distance across the page. Collecting a first frame of individual pixel data, mapping the first frame of individual pixel data into a pixel map memory, processing the first frame of individual pixel data to perform additional print quality features. These additional features can be categorized in three main categories: 1) sensing non-printing elements, 2) sensing pre-printed elements, and 3) sensing print elements.
