Abstract

A BT/USB image-printing converter and the method use a Bluetooth transmission module to receive image data from electronic products. According to a picture bridge protocol, the microprocessor converts the image data into printing data, which are then transmitted via a USB transmission module to the printing device. The printing of the image data is provided by electronic products without the aid of any computer device.

Claims

1. A BT/USB image-printing converter for a printing device, which comprises:

a Bluetooth transmission module, which receives image data transmitted from an electronic product by using a Bluetooth transmission function;

a microprocessor, which connects to the Blue transmission module to convert the image data into printing data; and

an universal serial bus (USB) transmission module, which connects to the microprocessor and is electrically coupled to the printing device for transmitting the printing data to the printing device.

2. The BT/USB image-printing converter of claim 1, wherein the microprocessor contains a memory unit for temporarily storing the image data.

3. The BT/USB image-printing converter of claim 1, wherein the microprocessor contains an extraction unit to extract image information to be printed from the image data.

4. The BT/USB image-printing converter of claim 3, wherein the image information to be printed is in the OPP (Object Push Profile) format.

5. The BT/USB image-printing converter of claim 3, wherein the image information to be printed is in the BIP (Basic Imaging Profile) format.

6. The BT/USB image-printing converter of claim 3, wherein the image information to be printed is in the BPP (Basic Printing Profile) format.

7. The BT/USB image-printing converter of claim 3, wherein the microprocessor contains a compiling unit for converting the image information to be printed into the printing data according to the picture bridge protocol (PBP).

8. The BT/USB image-printing converter of claim 1 further comprising a protection unit electrically coupling to the microprocessor and the USB transmission module to prevent the USB transmission module from transmitting too much electric power to the microprocessor.

9. The BT/USB image-printing converter of claim 1, wherein the format of the printing data is compliant with the PBP.

10. A BT/USB image-printing conversion method for a printing device coupled to a Bluetooth electronic product, comprising the steps of:

receiving image data transmitted from the electronic product using the Bluetooth transmission function;

extracting image information to be printed from the image data;

converting the image information to be printed into printing data according to the picture bridge protocol (PBP); and

transmitting the printing data to the printing device.

11. The BT/USB image-printing conversion method of claim 10 further comprising, before the step of receiving image data transmitted from the electronic product using the Bluetooth transmission, the steps of:

initializing the data transmission mode of the printing device; and

detecting the data transmission status of the electronic product.

12. The BT/USB image-printing conversion method of claim 10, wherein the step of receiving image data transmitted from the electronic product using the Bluetooth transmission contains the steps of:

temporarily storing the image data in a memory unit; and

checking the file format of the image data.

13. The BT/USB image-printing conversion method of claim 10, wherein the step of converting the image information to be printed into printing data according to the PBP contains the step of checking the file format of the printing data.

14. The BT/USB image-printing conversion method of claim 13, wherein the image information to be printed is in the OPP (Object Push Profile) format.

15. The BT/USB image-printing conversion method of claim 13, wherein the image information to be printed is in the BIP (Basic Imaging Profile) format.

16. The BT/USB image-printing conversion method of claim 13, wherein the image information to be printed is in the BPP (Basic Printing Profile) format.
