Abstract

A method, apparatus, and computer program product are described herein for controlling a printing device. In an example embodiment, a print line is divided into frames and frame dot states are determined based on neighboring frame dot states. Maximum motor speeds of the printing device may be adjusted so that actual motor speeds change gradually during printing. The print engine may detect a printhead type by sending a signal to the printhead and receiving a response. Motor torque is dynamically controlled based on type of media and/or labels present on the media.

First claim

That which is claimed:

1. A method for controlling motor torque of a printing device, the method comprising:
determining media information for a print job;
determining a starting torque of the print job based on the media information; and
dynamically calculating, via a logic circuit, a running torque for the print job based on the media information and the starting torque, wherein dynamically calculating the running torque comprises calculating a print surface torque based on…
