Abstract:
1. A mobile device for printing onto a print medium, the print medium including a linear-encoded data track extending in an intended direction of printing, the data track encoding at least a clock signal the mobile device including: a media feed path; at least two sensors in the media feed path configured to sense the data track of the print medium while the print medium is positioned in the media feed path; a fire control processor connected to the sensors to extract the clock signal from the linear-encoded data track, and to generate a fire control signal based upon the clock signal; a printhead for printing onto the print medium in response to the fire control signal, wherein the at least two sensors include a first sensor positioned ahead of the printhead in the intended direction of printing and a second sensor positioned after the printhead in the intended direction of printing, the clock signal being extracted from input from the first sensor before printing commences on a leading end portion of the print medium, and the clock signal being extracted from input from the second sensor while printing a trailing end portion of the print medium.
