Description

432817 V. Description of the invention (l) [Scope of application of the invention] The present invention relates to an infrared transmission printing server, especially suitable for receiving digital image data transmitted by the IrTran-P image transmission protocol, and can drive a printer Print the digital image data. [Background of the Invention] Due to the increasing demand for communication technology and communication, in addition to traditional radio transmission, 'infrared transmission has gradually begun to be applied to various information and home appliances', including digital cameras, notebook computers, mobile phones, etc. There is the same infrared IrDj (ln [rared Data Assoc interface. However, the IrDT ^ T message of the goal! Usually only uses f data transmission 'There is still a limit in the function side of image transmission f], therefore, At present, when the information environment is gradually moving towards broadband, digital, and multimedia, the traditional rDA protocol is not enough, so HP's JetSend and IrTran-P (Infrared Transfer Picture) ^ the rise of the image transfer agreement At present, because the IrTran-P image transmission protocol is developed and promoted by digital camera manufacturers in Japan, several digital cameras produced by Japanese manufacturers have been equipped with infrared IrDA interface and IrTran-P image transfer protocol, and Microsoft The company has incorporated the IfTran-P image transmission protocol into Windows 2000, and used Windows 2000 in this year ’s COMDEX Spring-Season Show to display the video data. Passing the Irran-P image to the image transmitted by the protocol. Therefore, compared to the competitors of other infrared image transmission protocols (such as Jetsend of P, etc.), the IrTran-P image transmission protocol is bound to become an untransmitted one. The mainstream of each infrared image transmission. —II —-“Figure 1” shows the protocol layers of IrD A and IrTran-P. Among them,

432B17 V. Description of Invention (2)

The IrDA protocol layer includes six layers between the Physical Layer and the IrCOMM Layer, while the IrTran-P includes SCEP, bFTP, and UPF. "Figure 2" shows the processing of digital image data in the digital image capture / output device and Windows2000. Among them, the digital image data is stored in the digital image capture / output device from UPF to Physical Layer. Joined the IrTran-P! I ^ rD A head end to identify and j quotient, and finally formed a string of infrared rays to reach a computer equipped with Windows 2000, after the computer received this data string 'then via Phy si ca 1 layer To UPF Layer ^ layer bar) _Except for the heads of Ir DA and IrTran-P 'to gradually filter the data and negotiate the transmission method, image format, etc.' Finally, the digital image data rolled out by the UPF Layer is passed through Wind 〇ws 2 0 0 0 The supported printing software is delivered to the printer. However, since Windows 2000 is not yet on the market, the use of the irTran-p image transmission protocol to transfer image data to a computer must be waited for after the release of wudo ews 2000, and this product must pass through IrDA within win ews 2000 2. The IrTran-P protocol processing layer can print images only by cooperating with the printer driver in the computer, as shown in the "3__". Anti-Xin users who have translation and whistle, want to print the number _Bit image must be equipped with a separate computer, which does not meet the δ cost considerations. Even for users who already have a computer, since the existing A computers are not yet equipped with I r D IrTra: 〇_-P transmission interface, so There are also inconveniences caused by computer printing. [Objective and Summary of the Invention] In view of the above-mentioned inconvenience of digital image printing, the main object of the present invention is to provide an infrared transmission printing servo device, which can communicate all
