Abstract
A method of updating resident firmware in a printer via a printer interface holding updated printer firmware includes automatically sending a request for printer hardware and firmware information to the printer. Printer hardware and firmware information received in response to the request is examined to determine if the updated printer firmware is compatible with the printer. If the updated printer firmware is not compatible with the printer, the updating is terminated. If the updated printer firmware is compatible with the printer, the updated printer firmware is automatically transmitted to the printer for storage therein.
Claims30
A method of updating firmware in a printer using a printer interface comprising:
- sending at least one query to the printer requesting information concerning the resident printer firmware stored therein;
- in response to the query, determining whether the resident printer firmware is to be updated;
- and
- if the resident printer firmware is to be updated, automatically transmitting updated printer firmware to the printer.
A method of updating resident firmware in a printer via a printer interface holding updated printer firmware comprising:
- automatically sending a request for printer hardware and firmware information to said printer;
- examining printer hardware and firmware information received in response to said request to determine if said updated printer firmware is compatible with said printer;
- if the updated printer firmware is not compatible with said printer, terminating said updating;
- and
- if the updated printer firmware is compatible with said printer, automatically transmitting said updated printer firmware to said printer for storage therein.
A printing device comprising:
- a printer having a processing unit, memory storing printer firmware executed by said processing unit and a printer control mechanism responsive to said processing unit and printing information on a medium;
- and
- a printer interface is coupled to said printer and having a processing unit and memory storing a printer firmware update routine, said printer firmware update routine being automatically executed when the memory of said printer interface holds updated printer firmware to effect loading of said updated printer firmware to said printer.
