Abstract
A hand-held micro-fluid ejection device for ejecting a fluid onto a substrate surface in a plurality of physical orientations between the ejection device and a substrate surface, and methods for controlling the geometric accuracy of printing using a hand-held printing apparatus. Various spatial and dynamic orientations of the ejection device are measured, such as rotation angle, yaw angle, and velocity and acceleration vectors. Threshold limits are established for the orientations and printing is disabled if the measured values exceed the threshold limits.
