Abstract
A print control apparatus includes a processor. The processor is configured to transmit generation condition data to a printer. The generation condition data includes a generation condition for a checksum value. The generation condition is based on identification information of the printer. The processor is also configured to check a first checksum value against a second checksum value to confirm the authenticity of the printer. The first checksum value is generated by the printer according to the generation condition. The second checksum value is generated according to the generation condition on the basis of the identification information of the printer.
Claims13
A print control apparatus comprising:
- a processor,
- wherein the processor is configured to
- transmit generation condition data to a printer, the generation condition data including a generation condition for a checksum value, the generation condition being based on identification information of the printer, and
- check a first checksum value against a second checksum value to confirm authenticity of the printer, the first checksum value being generated by the printer according to the generation condition, the second checksum value being generated according to the generation condition on a basis of the identification information of the printer.
A printer comprising:
- a processor,
- wherein the processor is configured to
- receive generation condition data including a generation condition for a checksum value, the generation condition being based on identification information of the printer,
- generate a checksum value according to the generation condition, and
- store the generated checksum value in such a manner that a print control apparatus is capable of obtaining the checksum value.
A print control system comprising:
- a printer that includes a processor and that performs printing;
- a print control apparatus that includes a processor and that controls printing performed in the printer,
- wherein the processor included in the print control apparatus is configured to
- transmit generation condition data to the printer, the generation condition data including a generation condition for a checksum value, the generation condition being based on identification information of the printer, and
- check a first checksum value against a second checksum value to confirm authenticity of the printer, the first checksum value being generated by the printer according to the generation condition, the second checksum value being generated according to the generation condition on a basis of the identification information of the printer, and
- wherein the processor included in the printer is configured to
- receive the generation condition data from the print control apparatus, the generation condition data including the generation condition for a checksum value, the generation condition being based on the identification information of the printer,
- generate the first checksum value according to the generation condition, and
- store the generated first checksum value in such a manner that the print control apparatus is capable of obtaining the first checksum value.
A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:
- transmitting generation condition data to a printer, the generation condition data including a generation condition for a checksum value, the generation condition being based on identification information of the printer;
- and
- checking a first checksum value against a second checksum value to confirm authenticity of the printer, the first checksum value being generated by the printer according to the generation condition, the second checksum value being generated according to the generation condition on a basis of the identification information of the printer.
A non-transitory computer readable medium storing a program causing a computer to execute a process comprising:
- receiving generation condition data including a generation condition for a checksum value, the generation condition being based on identification information of a printer;
- generating a checksum value according to the generation condition;
- and
- storing the generated checksum value in such a manner that a print control apparatus is capable of obtaining the checksum value.
