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.

Claims

1. 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.

2. The method of claim 1 wherein said at least one query comprises a request for printer hardware information from said printer, if the printer hardware information received from said printer indicates that the printer interface is not compatible with the printer hardware, said printer interface signaling an incompatible printer condition.

3. The method of claim 2 wherein signaling of said incompatible printer condition comprises at least one of illuminating a light source and sounding a sound emitting device.

4. The method of claim 3 wherein signaling of said incompatible printer condition comprises both illuminating a light source and sounding a sound emitting device.

5. The method of claim 3 wherein said light source is illuminated in a flashing pattern unique to said incompatible printer condition.

6. The method of claim 2 wherein signaling of said incompatible printer condition comprises commanding said printer to print a non-compatible printer message.

7. The method of claim 3 wherein signaling of said incompatible printer condition further comprises commanding said printer to print a non-compatible printer message.

8. The method of claim 1 wherein said at least one query comprises a request for printer firmware information from said printer, if the printer firmware information received from said printer indicates that the printer interface is not compatible with the printer firmware, said printer interface signaling an incompatible firmware condition.

9. The method of claim 8 wherein signaling of said incompatible firmware condition comprises at least one of illuminating a light source and sounding a sound emitting device.

10. The method of claim 9 wherein signaling of said incompatible firmware condition comprises both illuminating a light source and sounding a sound emitting device.

11. The method of claim 9 wherein said light source is illuminated in a flashing pattern unique to said incompatible firmware condition.

12. The method of claim 8 wherein signaling of said incompatible firmware condition comprises commanding said printer to print a non-compatible firmware message.

13. The method of claim 9 wherein signaling of said incompatible firmware condition further comprises commanding said printer to print a non-compatible firmware message.

14. The method of claim 1 wherein said at least one query comprises a request for printer configuration information from said printer, if the printer configuration information received from said printer indicates that the printer interface is not compatible with the printer configuration, said printer interface signaling an incompatible printer configuration condition.

15. The method of claim 14 wherein signaling of said incompatible printer configuration condition comprises at least one of illuminating a light source and sounding a sound emitting device.

16. The method of claim 15 wherein signaling of said incompatible printer configuration condition comprises both illuminating a light source and sounding a sound emitting device.

17. The method of claim 15 wherein said light source is illuminated in a flashing pattern unique to said incompatible printer configuration condition.

18. The method of claim 14 wherein signaling of said incompatible printer configuration condition comprises commanding said printer to print a non-compatible printer configuration message.

19. The method of claim 15 wherein signaling of said incompatible printer configuration condition further comprises commanding said printer to print a non-compatible printer configuration message.

20. The method of claim 1 further comprising:

prior to said sending said at least one query, attempting communications with said printer to detect hardware compatibility between said printer interface and said printer;

if said printer interface and printer are hardware compatible, sending said at least one query; and

if said printer interface and printer are not hardware compatible, skipping sending of said at least one query and signaling said non-compatible printer interface condition.

21. 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.

22. The method of claim 21 wherein said printer hardware and firmware information includes printer model and firmware version information.

23. The method of claim 21 wherein during examining the received printer hardware and firmware information is compared to lists of printer hardware and firmware information stored in said printer interface to detect coincidence.

24. The method of claim 23 further comprising:

prior to said sending said request, attempting communications with said printer to detect hardware compatibility between said printer interface and said printer;

if said printer interface and printer are hardware compatible, sending said request; and

if said printer interface and printer are not hardware compatible, skipping sending of said request and generating said output.

25. 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.

26. A printing device according to claim 25 wherein said printer interface includes at least one of a visual indicator and a sound emitting device responsive to said output to identify a non-compatible printer interface condition.

27. A printing device according to claim 26 wherein said at least one visual indicator is illuminated in a pattern unique to the type of non-compatible condition of said printer interface.

28. A printing device according to claim 27 wherein said printer interface non-compatible condition is a result of at least one of a printer hardware, printer firmware and printer configuration incompatibility.
