  • Patent number: 10386768
    Abstract: A printer controller determines whether a cartridge refilled with a recording material is mounted on an image forming apparatus. If it is determined that the cartridge refilled with the recording material is mounted on the image forming apparatus, control for shifting a printer engine to a predetermined state is performed, raw data is acquired from the printer engine that has been shifted to the predetermined state, and a user is notified of the degree of wear of the cartridge based on the acquired raw data. On the other hand, if the printer controller determines that the cartridge refilled with the recording material is not mounted on the image forming apparatus, the printer controller acquires a predicted value from the printer engine, and notifies the user of the degree of wear of the cartridge based on the predicted value.

  • Patent number: 10241731
    Abstract: An information processing apparatus has a printer driver and a device service associated with the printer driver as an output port of a print job generated by the printer driver. The printer driver receives data in accordance with a print instruction from an application operating on the information processing apparatus, generates a print job based on the received data, and outputs the print job to the output port. The print job is sent to the device service by an operating system using internal loopback. The device service connects to a print apparatus via a port that is different from the output port of the information processing apparatus, receives the print job from the printer driver, transmits a first control command for obtaining status information to the print apparatus, obtains the status information of the apparatus, and accepts print data received through a receiving port.
