Abstract
A method of detecting printer interface and printer incompatibility comprises automatically sending a request for printer hardware and firmware information to the printer upon initialization of the printer interface in the printer. The printer hardware and firmware information received in response to the request is examined to determine if the printer interface is compatible with the printer. Output is generated when the printer interface is not compatible with the printer.
Claims28
A method of detecting printer interface and printer incompatibility comprising:
- sending at least one query from the printer interface to the printer requesting information concerning the printer;
- in response to the query, determining whether the printer interface is compatible with the printer;
- and
- if the printer interface is not compatible with the printer, signaling a non-compatible printer interface condition.
A method of detecting printer interface and printer incompatibility comprising:
- automatically sending a request for printer hardware and firmware information to said printer upon initialization of the printer interface in said printer;
- examining the printer hardware and firmware information received in response to said request to determine if the printer interface is compatible with said printer;
- and
- generating output when said printer interface is not compatible with said printer.
A printing device comprising:
- a printer having a processing unit, memory storing printer firmware executed by the processing unit and a printer control mechanism responsive to the processing unit and printing information on a medium;
- and
- a printer interface coupled to the printer and including a processing unit and memory storing a printer interface compatibility determination procedure, said printer interface compatibility determination procedure being automatically executed when the printer interface is initialized to determine whether the printer interface is compatible with the printer, said processing unit generating output when said printer interface is not compatible with said printer.
