US Patent 11126385 Firmware upgrade system and associated methods for printing devices

A system of printing devices includes an analytical server that determines when a firmware upgrade is to be installed on one or more of the printing devices. The analytical server collects information about firmware version and type along with errors that occur on the printing devices. The analytical server also collects information on the print volume for each device. A map is generated and updated based on this information that is used to decide when or if the firmware upgrade is to occur. For a first printing device and a second printing device, the analytical server determines whether to upgrade different versions of the firmware at each device.
