Abstract
An optical communication system for a printer includes an infrared light emitting diode for emitting a radiation for transmitting a printing data, an infrared receiver for receiving the printing data transmitted with the radiation, a printer body to which the printing data is supplied through the infrared receiver, a microcomputer for detecting a state of data transmission of the printing data, an indicator light emitting diode for indicating the state of transmission in accordance with the microcomputer so that the state of printing data transmission is visible to a user.
Claims12
A radio communication system for a printer, comprising:
- means for emitting a radiation for transmitting a printing data;
- means for receiving said printing data transmitted with said radiation;
- a printer body to which said printing data is supplied through said receiving means, said receiving means comprising an adapter detachably attached to said printer body;
- means for detecting a state of data transmission of said printing data;
- and
- means provided on said adapter for indicating said state of transmission in accordance with said detecting means so that said state of printing data transmission is visible to a user, said indicating means being activated when said detecting means detects said state of data transmission;
- wherein said adapter includes means for emitting a response data to said means for emitting a radiation.
A method for indicating a state of printing data transmission in a radio communication system for a printer, said method comprising the following steps:
- (1) providing a printing data in a packet data form;
- (2) checking a transmission state of said printing data;
- (3) turning an indicator ON to visibly indicate a normal printing data transmission when said printing data is being properly transmitted;
- (4) turning said indicator OFF to indicate the end of said printing data transmission when the last block of said printing data in said packet form has been transmitted;
- (5) turning said indicator flickered to visually indicate a malfunction of said printing data transmission if said indicator is instructed to be turned ON according to said step (3) and a lapse of a predetermined time.
