Method of Rewriting Printer Firmware, and Printer |
| 摘要 |
A printer having multiple processor cores, and a firmware rewriting method for the printer, enable rewriting firmware in a short time. A first rewrite controller 74 controls rewriting the firmware of the first core by the boot program of the first core; a second rewrite controller 75 controls rewriting the firmware of a second core, which is one of the multiple cores other than the first core, by the boot program of the first core; and a reset unit 76 resets the printer after rewriting the firmware of the first core and the firmware of the second core by the boot program of the first core ends. |
