Inkjet printer, ink billing system, and inkjet printer control method

摘要

A printer and printer control method can report information about ink consumption to a host computer (300. The printer (100) is communicatively connected to the host computer (300), and prints according to print jobs received from the host computer (300). The printer (100) has a job data storage unit (190) for storing information about each print job. A reception unit (110) receives the print jobs from the host computer (300). A print control unit (150) controls printing on paper using a predetermined ink according to the print job. A printing evaluation unit (175) evaluates the result of printing a print job. A ink shot count conversion unit (170) calculates the number of ink shots used to print the print job. A job data management unit (180) stores the job ID for the print job and the ink shot count used to print the print job linked to the print result determined for printing the print job in the job data storage unit (190).
