Title:
FIRMWARE-UPDATING SYSTEM AND UPDATE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2016/006268
Kind Code:
A1
Abstract:
The present invention makes it possible to update firmware regardless of whether a printer is online or not. The present invention transmits a firmware forced update command to a printer (200) via a first transmission path (control pipe of USB cable (300)) capable of transmitting a command regardless of the state of the printer (200), switches the printer (200) to an online state, and thereafter, updates by transmitting firmware to the printer (200) via a second transmission path (bulk-out pipe of USB cable (300)). As a result, even when the printer (200) is offline, it is possible to update the firmware regardless of whether the printer (200) is online or not, by forcibly switching the printer (200) to an online state by using a firmware forced update command transmitted through the control pipe, and achieving a state from which a firmware update is possible.
