Abstract

A controller is provided for encoding tags to be printed by a printhead controlled by the controller. The controller has an input at which to receive a tag structure template having at least one predetermined mark position, an input at which to receive fixed data bits, an input at which to receive variable data bits, and a dot generator which uses the input tag structure template, and fixed and variable data bits for outputting, for at least one mark position of a respective tag, a single bit indicating if a dot is to be provided at the at least one mark position, for the respective tag.

Claims

1. A controller for encoding tags to be printed by a printhead controlled by the controller, the controller comprising:

an input at which to receive a tag structure template having at least one predetermined mark position;

an input at which to receive fixed data bits;

an input at which to receive variable data bits; and

a dot generator which uses the input tag structure template, and fixed and variable data bits for outputting, for at least one mark position of a respective tag, a single bit indicating if a dot is to be provided at the at least one mark position, for the respective tag.

2. A controller according to claim 1, comprising a redundancy encoder for optionally encoding the fixed and variable data bits.

3. A controller according to claim 2 wherein the redundancy encoder uses Reed-Solomon encoding.

4. A controller according to claim 1 wherein tags are placed regularly on a page.

5. A controller according to claim 4 wherein tags are placed in a triangular grid.
