Abstract

There is provided a printer, in which print data from an external electronic appliance is transmitted to a computer and processed therein, and the processed data is supplied to a printing unit, and then a picture based on that processed print data can be printed by means of the printing unit. This printer includes a parallel I/O terminal (or serial I/O terminal) to which a computer is connected, a built-in infrared ray transmitter/receiver to which the external electronic appliance having an infrared ray transmitter/receiver is connected through the infrared ray transmitter/receiver, a first transmitting path for connecting the parallel I/O terminal (or serial I/O terminal) and the built-in infrared ray transmitter/receiver, and a second transmitting path for connecting the parallel I/O terminal (or serial I/O terminal) and the printing unit.

Claims

1. A printer for printing an image and connectable at an input/output terminal to a computer that can receive transformed print data, process the transformed print data and output processed print data, the printer comprising:

a cordless link that receives print data from an external appliance and transmits the print data along a first transmitting path;

a data transforming device connectable to the first transmitting path that receives the print data and outputs transformed print data along a second transmitting path, said second transmitting path connectable to the input/output terminal; and

a printing unit that receives the processed data from the data transforming device by way of a third transmitting path and prints the image;

whereby after the computer receives and processes the transformed print data, the computer outputs the processed data to the input/output terminal and the second transmitting path, said data transforming device receives the processed data from the second transmitting path and outputs the processed data along a third transmitting path, and

said printer acting as a conduit for said print data from the external appliance to said computer.

2. The printer of claim 1 wherein said cordless link is a bi-directional infrared communications link.

3. The printer of claim 2 wherein the input/output terminal is connectable to a parallel printer port.

4. The printer of claim 2, wherein the input/output terminal is connectable to a serial printer port.

5. The printer of claim 2, wherein at least one of the first, second and third transmitting paths is bi-directional.

6. A printer for printing an image comprising:

a cordless link that receives print data from an external appliance and transmits the print data along a first transmitting path;

a first data transforming device connectable to the first transmitting path that receives the print data and outputs first transformed print data along a second transmitting path;

a second data transforming device connectable to the second transmitting path that receives the first transformed print data and outputs second transformed print data along a third transmitting path;

an input/output terminal connectable to the third transmitting path and connectable to a computer, whereby the second transformed print data is transmitted to the computer for processing into processed print data, the processed print data from the computer is output to the third transmitting path and to the second data transforming device, said second data transforming device receives the processed print data and outputs transformed processed print data along a fourth transmitting path; and

a printing unit connectable to the fourth transmitting path that receives the transformed processed data and prints an image of the transformed processed print data;

said printer acting as a conduit for said print data from the external appliance to said computer.

7. The printer of claim 6, wherein the first transmitting path is a serial transmitting path, the second transmitting path is a parallel transmitting path, the third transmitting path is a serial transmitting path, and the fourth transmitting path is a parallel transmitting path.

8. The printer of claim 6, wherein the input/output terminal is a parallel terminal.

9. The printer of claim 6, wherein the input/output terminal is a serial terminal.

10. The printer of claim 6, wherein said cordless link is a bi-directional infrared communications link.

11. The printer of claim 6, wherein at least one of the first, second, third and fourth transmitting paths is bi-directional.

12. A printer system for printing an image comprising:

a cordless link that receives print data from an external appliance and transmits the print data along a first transmitting path;

a first data transforming device connectable to the first transmitting path that receives the print data and outputs first transformed print data along a second transmitting path;

a second data transforming device connectable to the second transmitting path that receives the first transformed print data and outputs second transformed print data along a third transmitting path;

an input/output terminal connectable to the third transmitting path that receives the second transformed print data;

a computer connectable to the third transmitting path that receives the second transformed print data, processes the transformed print data into processed print data and outputs the processed print data to the third transmitting path to the second data transforming device, said second data transforming device receives the processed print data and outputs transformed processed print data along a fourth transmitting path; and

a printing unit connectable to the fourth transmitting path, that receives the transformed processed data and prints an image of the transformed processed print data;

said printer acting as a conduit for said print data from the external appliance to said computer.

13. The printer system of claim 12, wherein the electronic appliance is one of an electronic still camera, a television, a video tape recorder, a facsimile machine, a telex machine, and an internet appliance.

14. A method of printing comprising the steps of:

generating a command signal to transmit print data and sending said command signal to an electronic appliance along a first bi-directional transmitting path, said bi-directional path located in a printer;

transmitting said print data from the electronic appliance along the first bi-directional transmitting path to a computer;

processing the print data at the computer and outputting processed print data;

transmitting said processed print data from the computer along a second transmitting path to a printing unit; and

receiving the processed print data at the printing unit and printing an image based on the processed print data.
