Abstract
A printer including a printing execution unit configured to execute printing; a code conversion unit configured to encode operational information in relation to the printing execution unit to generate an image pattern; and a display unit configured to display the image pattern, generated by the code conversion unit, on the display unit itself.
Claims5
A printer comprising:
- a printing execution unit comprising a print head and configured to execute printing;
- a code conversion unit configured to encode operational information in relation to the printing execution unit to generate an image pattern;
- a display configured to display the image pattern, generated by the code conversion unit, on the display itself;
- and
- an input operation unit configured to receive an input operation;
- wherein the code conversion unit is further configured to encode the operational information into an image pattern representing a plurality of pieces of information by at least one color difference, and adjust, in accordance with the input operation received by the input operation unit, a degree of the at least one color difference included in the image pattern to allow the plurality of pieces of information to be discriminated.

A terminal device comprising:
- a read unit that comprises a camera and is configured to read an image pattern resulting from (i) encoding operational information in relation to a printer that performs printing into an image pattern representing a plurality of pieces of information by at least one color difference, and (ii) adjusting, in accordance with an input operation received by an input operation unit, a degree of the at least one color difference included in the image pattern to allow the plurality of pieces of information to be discriminated;
- and,
- a decode unit configured to decode the image pattern, obtained through the reading by the read unit.
