  • Patent number: 11714582
    Abstract: A virtual printer A generated in a virtual printer service included in a host computer including an OS uses a search request receiver to receive a device search request from the OS, and uses a search request responder to respond to the received device search request. Further, a print job receiver receives a print job from the OS, which has registered the virtual printer A as a transmission destination of the print job based on the response, in accordance with a specific protocol. Then, a print job converter converts the received print job, and a print job transmitter transmits the converted print job to a printer AY, which does not support the specific protocol, via a job generator in accordance with a protocol different from the specific protocol.
