Fig. 2 is the stereogram of the utility model body part, comprises body 30, is provided with a circuit arrangement (not shown) in the described body 30, and described body 30 also is provided with two joints 31,32, can be connected to USB port 10 or parallel port mutually with printer 1 respectively.
The utility model is characterised in that, described two joints 31,32 are located on the body 30 and with described circuit arrangement and link to each other, make body 30 can pass through one of them joint 31 or another joint 32, convert the signal of the USB port 10 of described printer 1 or parallel port to behind the blue tooth wireless communication protocol signal wireless wireless network card that is sent to described main frame 2 via described circuit arrangement, or the signal that sent according to the blue tooth wireless communication agreement of wireless transmission via described wireless network card of receiving computer main frame 2, and convert thereof into the signal of USB port 10 or parallel port, be input into the USB port 10 or the parallel port of described printer 1.
The most basic standard of Bluetooth technology is universal access standard (GAP, Generic Access Profile), and other all standard all base is used its function thereon.The purpose of universal access standard (GAP, GenericAccess Profile) is to determine that all devices can successfully set up the fundamental frequency link.
The utility model can use two kinds of Bluetooth specifications, and serial port standard and hard copy cable replace standard, as the radio communication specification of printer operation 1.Bluetooth 1.0 editions, be established in the serial port standard on the universal access standard, the RS232 serial cable that simulation is provided is to blue-tooth device, be the wireless network card 20 and the body 3 that the utlity model has the bluetooth printer exchanging structure of double nip of main frame 2 installings, use the serial port of RFCOMM simulation.In this mode, the former application program of writing (legacy) needn't change for using bluetooth, because of it can simply regard linking bluetooth as the serial cable link.The serial port standard is supported the device of two kinds of kenels: first kenel: as communication terminal device, as notebook computer, printer etc. and second kenel: as the middle device of part communication link, as modem.Simulate the first kenel device and can make the program of bluetooth support based on serial port.
Fig. 3 uses the RFCOMM Communication Layer of serial port standard first kenel for the utility model.For the utility model embodiment, the serial port standard is with RFCOMM Communication Layer simulation serial port, main frame 2 (to call initiator (initiator) in the following text), set up the RFCOMM communication line, the utlity model has the body 3 (to call respondent (responder) in the following text) of the bluetooth printer exchanging structure of double nip, be connected in printer 2.The initiator sets virtual serial port and wants several steps with setting up communication line, sets virtual serial port and the flow chart of setting up communication line with reference to Fig. 4 the utility model:
Step 1: the address of finding the blue-tooth device of the communication line other end.Can inquire that the back chosen by the user, the user imports the address of blue-tooth device, or pairing in advance is good and without Asking About The Address 41.
Step 2: comprise three sub-steps:
2a) call out the ACL communication line 420 that the device of having chosen is set up fundamental frequency.
2b) build the L2CAP channel to SDP (ServiceDiscovery Protocol) server 422.
2c) the channel number 424 of SDP (Service Discovery Protocol) acquisition RFCOMM server.
Step 3: the respondent will set up a L2CAP channel to RFCOMM43, to activate the multiplexer transmission of RFCOMM.
Step 4: force to support safety measure 44: use a shared secret PIN or require fundamental frequency to encrypt.
Application software is with UIH (Unnumbered Information withHeader) communication format, at the RFCOMM channel by virtual serial port communication.
The utility model also can use hard copy (Hardcopy) cable to replace standard, can directly use the driver of printer to come printed information on client.Hard copy (Hardcopy) cable replaces standard and can facilitate the driver of direct use printer on the main frame end to print.Hard copy (Hardcopy) cable replaces the standard support with a 1284ID character string, discerns a driver, and this character string is used for describing the type and the specification of printer, and the flow-control of simple basis of credit also is provided.Hard copy (Hardcopy) cable replacement standard can be handled the broken string problem in print job, and the incident that also can allow the client registration pay close attention to allows printer side during operation, when incident takes place, transmits an asynchronous notice.
The communications protocol that hard copy (Hardcopy) cable replaces standard needs an application program, normally a printed driver at main frame 2 ends.At printer 1 end, application program may be a Command Interpreter or other program.Hard copy (Hardcopy) cable replaces standard and relies on the correct driver of installation, and supports to discern driver with a 1284ID character string.
Hard copy (Hardcopy) cable replaces standard provides the flow-control of simple basis of credit.Can handle the broken string problem in print job, can allow also client registration pays close attention to incident-this will allow printer 1 during operation, when the utility model takes place in incident, transmit an asynchronous notice.
Hard copy (Hardcopy) cable replaces standard and uses three channels: data channel (data channel), control channel (control channel) and notification channel (notification channel).
One, data channel (data channel) is used for the printer emulation cable, and to transmit undressed particular data, wherein the data format of Chuan Songing is decided according to printer 1 driver, does not have specific form.
Two, control channel (control channel) is independent of data channel, the driver kenel of identification printer 1, obtains status information, handles flow-control, requires notice and handles reset (reset).Therefore control printer 1 and must not wait for the end that transmits print data.Control channel provides standard defined control signal, comprises the basis of credit flow-control and allows the utility model from main frame 2 ends that printer 1 notice transmits, and prints " notification characteristic " of dependent event.
Three, notification channel (notification channel) in order to load from printer 1 to main frame 2 asynchronous event notice.
Fig. 5 is the hardware structure diagram of the utility model body part.The utility model body part is integrated in a circuit arrangement 50 with bluetooth module and control module, control module comprises an integrated circuit, be located at body 30 inside, body 30 also has two joints, a joint is that USB joint 31, another joint are parallel port joint 32, can be connected to its USB port 10 or parallel port mutually with printer 1 respectively, two joints divide other other end to link to each other with described control module.
More than be an embodiment of the present utility model, but foregoing is not in order to limit the utility model, any change or the modification done in design that does not break away from the utility model and disclosed and scope of the those of ordinary skill of any industry all must be in scope of the present utility model.
