Printing system, printer, printing control method of printing system, and program

A printer for performing a printing process on the basis of generated printing data, comprising:

• an information-at-generation obtaining section for obtaining management information of the printer when the printing data is generated;
• a printing data generating section for generating the printing data on the basis of the obtained management information;
• a printing start instructing section for instructing start of printing based on the printing data;
• a printing control section for performing the printing process on the basis of the printing start instruction;
• an information-at-start obtaining section for obtaining management information of the printer when the printing start is instructed;
• and
• a management information determining section for determining whether the management information obtained when the printing data is generated and the management information obtained when the printing start is instructed coincide with each other,
• wherein the printing control section is configured to cancel the printing process in a case where the management information obtained when the printing data is generated and the management information obtained when the printing start is instructed do not coincide with each other, as a determination result in the management information determining section.

A printing control method for controlling a printer which performs a printing process on the basis of generated printing data, the method comprising:

• obtaining management information of the printer when the printing data is generated;
• generating the printing data on the basis of the obtained management information;
• obtaining a start instruction of printing based on the printing data;
• outputting a printing start command to the printer on the basis of the printing start instruction;
• obtaining management information of the printer when the printing start instruction is obtained;
• determining whether the management information obtained when the printing data is generated and the management information obtained when the printing start instruction is obtained coincide with each other;
• and
• canceling the printing start command to the printer in a case where the management information obtained when the printing data is generated and the management information obtained when the printing start instruction is obtained do not coincide with each other, as a determination result.
