Abstract
An image forming apparatus includes a first printer configured to print on a medium using a first material, a second printer configured to print on the medium using a second material that turns invisible when a first condition is satisfied, and a controller configured to: control the first printer to print on the medium a first symbol that is machine-readable and associated with first information, and control the second printer to print a second symbol on the medium on which the first symbol has been printed. A composite symbol of the first and second symbols is machine-readable and associated with second information different from the first information.
Claims18
An image forming apparatus comprising:
- a first printer configured to print on a medium using a first material;
- a second printer configured to print on the medium using a second material that turns invisible when a first condition is satisfied;
- and
- a processor configured to:
- control the first printer to print on the medium a first symbol that is machine-readable and associated with first information, and
- control the second printer to print a second symbol on the medium on which the first symbol has been printed, wherein a composite symbol of the first and second symbols is machine-readable and associated with second information different from the first information, wherein
- the first symbol is readable by an information processing apparatus and causes the information processing apparatus to display the first information when read by the information processing apparatus, and
- the composite symbol is readable by the information processing apparatus and causes the information processing apparatus to display the second information when read by the information processing apparatus.
An image forming apparatus comprising:
- a first printer configured to print on a medium using a first material;
- a second printer configured to print on the medium using a second material that turns invisible when a first condition is satisfied;
- a third printer configured to print on the medium using a third material that turns invisible when a second condition different from the first condition is satisfied;
- and
- a processor configured to:
- control the first printer to print on the medium a first pattern,
- control the second printer to print a second pattern on the medium on which the first pattern has been printed, wherein a first composite pattern of the first and second patterns is machine-readable and associated with first information, and
- control the third printer to print a third pattern on the medium on which the first and second patterns have been printed, wherein a second composite pattern of the first and third patterns is machine-readable and associated with second information different from the first information.
A printing medium comprising:
- a base;
- a first symbol that is printed on the base, formed of a first material, and machine-readable and associated with first information;
- and
- a second symbol that is printed on the base and formed of a second material turning invisible when a first condition is satisfied, wherein a composite symbol of the first and second symbols is machine readable and associated with second information different from the first information, wherein
- the first symbol is readable by an information processing apparatus and causes the information processing apparatus to display the first information when read by the information processing apparatus, and
- the composite symbol is readable by the information processing apparatus and causes the information processing apparatus to display the second information when read by the information processing apparatus.
