Devices and methods for acquiring model information of a peripheral device by a computer

摘要

Device and methods for acquiring by a host device model information (model ID) of a device assigned in a new range are provided herein. In many embodiments, the device includes a model information storage unit that stores model information from either a first range or a second range outside the first range and a communication unit that communicates with a device that requests model information, receives a model information request, and in response returns the model information if within the first range and returns specific information if the model information is outside the first range. After the specific information is sent, a new request is sent from the host device after which the communication unit provides the model information within the second range, often in a different format from the specific information.

主权项

1. A printing device having a model ID and that is capable of communicating with a host computer and comprising:
a print unit; a model information storage unit that stores model information for the printing device, wherein the model information corresponds to the model ID; a communication unit that receives information from and sends information to the host computer; and a control unit configured to:
(i) receive a first transmission request from the host computer for model information within a first range in a first format;(ii) send the model information through the communication unit to the host computer in the first format in response to the first transmission request, wherein
when the model ID is within the first range in the first format, which corresponds to a legacy device model ID, sending the model information comprises sending the model ID to the host computer, andwhen the model ID exceeds the first range within the first format, which corresponds to an advanced device model ID, sending the model information comprises sending specific information in the first format in the first range of values indicating there is model information in a second range of values in response to the transmission request;(iii) receive a second transmission request from the host computer for model information exceeding the first range after sending the specific information when the model ID exceeds the first range in the first format;(iv) send the model information exceeding the first range to the host computer from which the advanced device model ID is obtained; and(v) receive a write program command of a control program selected based on the model ID of the printing device.
