Abstract
Provided are a method and apparatus for performing diagnostic functions of an external device such as a printer, connected to a host computer. The apparatus and method receive information about diagnostic functions supported by the external device from the external device; receive one or more of the diagnostic functions which are selected by a user; request the external device to perform the selected diagnostic functions; and receive the results of the requested diagnostic functions from the external device.
Claims19
A method of performing diagnostic functions of an external device in a host computer, the method comprising:
- receiving information about diagnostic functions supported by the external device from the external device;
- receiving one or more of the diagnostic functions which is selected by a user;
- requesting the external device to perform the selected diagnostic functions;
- and
- receiving the results of the requested diagnostic functions from the external device.
An apparatus for performing diagnostic functions, the apparatus being included in an external device connected to a host computer and comprising:
- a memory which stores information about diagnostic functions supported by the external device;
- a diagnosis processing unit which receives information about the diagnostic functions from the memory and performs a diagnostic function requested by the host computer using the information;
- and
- a data input/output unit which receives the information about the diagnostic functions from the diagnosis processing unit, outputs the information to the host computer, receives the diagnostic functions requested by the host computer, and outputs the results of the requested diagnostic functions to the host computer.
A diagnostic system for performing diagnostic functions of an external device by using a host computer, the diagnostic system comprising:
- a host computer which receives information about supported diagnostic functions from the external device, requests the external device to perform at lest one of the diagnostic functions, and receives the result of the selected diagnostic functions from the external device;
- and
- an external device which outputs information about supported diagnostic functions to the host computer, and outputs the diagnosis result to the host computer after performing the selected diagnostic functions requested by the host computer.
A computer readable medium of instructions for controlling a diagnosis system comprising a host computer and at least one external device connected to the host computer, comprising:
- a first set of instructions adapted to control the host computer to receive information about diagnostic functions supported by the at least one external device from the external device;
- a second set of instructions adapted to control the host computer receive a selection of one or more of the diagnostic functions which are selected by a user;
- a third set of instructions adapted to control the host computer to request the external device to perform the selected diagnostic functions;
- and
- a fourth set of instructions adapted to control the host computer to receive the results of the requested diagnostic functions from the external device.
