Abstract

A method of using a mobile device to determine movement, relative to the mobile device, of a print medium configured to be printed on by the mobile device in a print direction, the mobile device including a printer, a first sensor and processing means, the print medium comprising a substrate defining first and second opposite faces, the first face bearing coded data, the method comprising the steps of: using the first sensor to sense at least some of the coded data from the print medium; determining movement of the print medium relative to sensor, based on the coded data sensed by the first sensor.

Claims

1. A method of using a mobile device to determine movement, relative to the mobile device, of a print medium configured to be printed on by the mobile device in a print direction, the mobile device including a printer, a first sensor and processing means, the print medium comprising a substrate defining first and second opposite faces, the first face bearing coded data indicative of a plurality of locations associated with the print medium, the coded data taking the form of a two-dimensional array of data, the method comprising the steps of:

using the first sensor to capture a plurality of images of subsets of the coded data on the print medium;

decoding the subsets of the coded data in order to determine a plurality of locations; and

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

2. 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 first sensor senses the coded data.

3. 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.

4. 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.

5. 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.

6. A method according to claim 5, wherein the at least one orientation indicator is disposed at or adjacent an edge of the print medium.

7. A method according to claim 1, further including the steps of using the processing means to determine, from a known physical orientation of the print medium and the first image, a first relative rotation of the coded data with respect to the print medium.

8. A method according to claim 1, further including the steps of:

using a second sensor to capture a second image of at least some of the coded data; and

determining movement of the print medium relative to sensor, based on the coded data sensed by both the first and second sensors.
