Abstract

A method of using a mobile device to determine movement, relative to the mobile device, of a print medium being printed on by the mobile device is disclosed. The mobile device includes a printer. The mobile device further includes a sensor in a media feed path of the printer and a processing means. A surface of the print medium bears coded data indicative of a plurality of locations on the surface. The method uses the sensor to sense the coded data at a plurality of locations on the surface. The sensed coded data is decoded in order to determine the locations, and the movement of the print medium relative to sensor is determined from the locations.

Claims

1. A method of using a mobile device to determine movement, relative to the mobile device, of a print medium being printed on by the mobile device, the mobile device including a printer, a sensor in a media feed path of the printer and processing means, a surface of the print medium bearing coded data indicative of a plurality of locations on the surface, the method comprising the steps of:

using the sensor to sense the coded data at a plurality of locations on the surface;

decoding the coded data at respective locations in order to determine the plurality of locations; and

determining movement of the print medium relative to the sensor from the locations.

2. A method according to claim 1, wherein the coded data takes the form of a two-dimensional array.

3. A method according to claim 1, the mobile device further including a light emitting device, the method including the step of using the light emitting device to illuminate the print medium while the sensor senses the coded data.

4. A method according to claim 1, further including the steps of generating a clock signal based on the movement, and using the clock signal to synchronize the printing onto the print medium.

5. A method according to claim 1, including the step of printing onto the print medium and performed during printing onto the print medium, the steps of:

using the processing means to generate a clock signal based on the locations; and

using the clock signal to synchronize the printing onto the print medium.

6. A method according to claim 1, wherein the print medium includes at least one orientation indicator indicative of an orientation of the print medium, the method comprising determining the orientation from the orientation indicator before commencing printing.

7. A method according to claim 6, wherein the at least one orientation indicator is disposed at or adjacent an edge of the print medium.
