Detailed Description
In order that the manner in which the above recited features and advantages of the invention are obtained will be readily understood, a more particular description of the invention will be rendered by reference to the appended drawings. The detailed description is merely intended to facilitate an understanding of the invention and the scope of the invention is not limited to the specific description of the embodiments.
It should be noted that the terms "first," "second," and the like in the claims, specification, and abstract of this application are used to distinguish between similar objects, and are not necessarily used to describe a particular order or sequence.
Fig. 1 shows a specific embodiment of a multi-connection data management method of a bluetooth printer according to the present invention, in which the method mainly includes the following steps:
step S101: and establishing connection.
The Bluetooth printer (Bluetooth printer) is used for applying the Bluetooth technology to the printer, so that inconvenience brought by connecting the printer is eliminated, wireless printing is realized, the influence of cables can be reduced, and the printer can be moved away from a host at will. The Bluetooth printer mainly comprises a Bluetooth module and a printing module, wherein the Bluetooth module is responsible for data transmission, and the printing module is responsible for data printing.
In one embodiment of the invention, a bluetooth printer and at least two bluetooth devices each establish a bluetooth link, the purpose of this step being to provide for the transmission of print data.
In one particular embodiment of the invention, the Bluetooth device comprises a classical Bluetooth device and/or a low energy Bluetooth device. The bluetooth device may be a bluetooth mobile phone, a bluetooth computer, a bluetooth headset, etc. A Bluetooth printer can be connected with 8 Bluetooth devices, including 7 classical Bluetooth devices and 1 low-power Bluetooth device.
Step S102: and a print data transmission step.
In this embodiment, at least two bluetooth devices print simultaneously, that is, all bluetooth devices transmit first print data simultaneously, wherein the first print data is the first print data transmitted by each bluetooth device to the bluetooth printer. The purpose of this step is to provide the possibility for multiple bluetooth devices to print simultaneously.
Then, the bluetooth module sequentially receives the first print data sent by each bluetooth device, and then adds all the first print data to the data link list. The purpose of this step is to know the time of receipt of the print data for each bluetooth device and to ensure that the print data for each device is successfully sent.
Step S103: printing a first step.
In this embodiment, the bluetooth module uses the first print data received first as the current print data, uses the bluetooth link corresponding to the current print data as the current link, and uses one bluetooth device corresponding to the current link as the current bluetooth device according to the receiving time sequence. And then the Bluetooth module sends the current printing data to a printing module in the Bluetooth printer, at the moment, the data link list automatically deletes the first printing data sent to the printing module, and the printing module receives and executes the printing function. And in the printing process, the Bluetooth module continuously receives second printing data in the current Bluetooth device and adds the second printing data into the data link list. When the Bluetooth module sends the second printing data to the printing module, the data link list deletes the second printing data, and the printing module receives and prints the second printing data. After the second printing data in the current Bluetooth device is printed, the Bluetooth module judges that the printing data in the current Bluetooth device is sent completely after the next printing data corresponding to the current Bluetooth device is not received in the preset time, wherein the second printing data is the printing data of the first printing data removed from each Bluetooth device. Preferably, the preset time is 2s.
Meanwhile, in order to avoid the occurrence of printing disorder, in the printing process of the first current Bluetooth device, the Bluetooth module can prevent other unprinted Bluetooth devices from sending second printing data to the Bluetooth module in a flow control mode. The purpose of this process is to ensure that after the data of one bluetooth device is printed, the data of the next bluetooth device is printed.
Step S104: and printing a second step.
In this embodiment, when the first step of printing is completed, the bluetooth module uses the first print data received first as the current print data, uses the bluetooth link corresponding to the current print data as the current link, and uses the bluetooth device corresponding to the current link as the current bluetooth device in the remaining first print data of the data link list. And then the Bluetooth module sends the current printing data to the printing module, at the moment, the data link list automatically deletes the first printing data sent to the printing module, the printing module receives and executes the printing function, and in the printing process, the Bluetooth module resumes the transmission of the second printing data in the current Bluetooth device in a Bluetooth flow control mode and adds the second printing data to the data link list. When the Bluetooth module sends the second printing data to the printing module, the data link list deletes the second printing data, and the printing module receives and prints the second printing data. After the second printing data is printed, the next printing data in the current Bluetooth device is not received within the preset time, and the fact that the printing data in the current Bluetooth device are sent is indicated. Preferably, the preset time is 2 seconds.
Step S105: and (5) circulating.
And in the remaining unprinted Bluetooth devices, the Bluetooth printer repeatedly prints the second step according to the time sequence of receiving the first printing data until the printing data in each Bluetooth device is printed.
The printing of a plurality of Bluetooth devices can be sequentially realized through the management of printing data and output by the Bluetooth flow control mode of the method, and the condition of disordered printing can be effectively avoided.
The following describes a data management method for multiple connections of a bluetooth printer according to an embodiment of the present invention.

Printing the first step, the Bluetooth module transmits the printing data according to the receiving time sequence, if the Bluetooth module receives the first printing data A first 1 First print data A 1 As current print data, bluetooth link a is taken as the current link, and a is taken as the current bluetooth device. The Bluetooth module prints the first print data A 1 The link list is automatically deleted A and sent to a printing module in a Bluetooth printer 1， Printing module Process A 1 When A is printing of 1 After printing, the Bluetooth module continues to receive the second printing data A in A 2 And send to the printing module for printing, print data A 2 After printing, the Bluetooth module continues to receive the second printing data A in A 3 And send to the printing module to print, so cycle until the Bluetooth module does not receive the second printing in A for more than 2sNext print data a corresponding to print data An n+1 And judging that all the printing data in the A are printed. Meanwhile, in the printing process of the printing data in the A, the Bluetooth module can prohibit the B from sending the second printing data Bn to the Bluetooth module in a Bluetooth flow control mode.
A second printing step, when the printing data in A is printed, the Bluetooth module receives the printing data B 1 As the current print data, bluetooth link B is taken as the current link, and B is taken as the current bluetooth device. The Bluetooth module prints the data B 1 Sending the data to a printing module for printing, and automatically deleting the linked list B 1 . Print data B 1 In the printing process, the Bluetooth module resumes the transmission of the printing data in the B through the Bluetooth flow control mode. The Bluetooth module receives the printing data B in B 2 And send to the printing module for printing, print data B 2 After printing, the Bluetooth module continues to receive the printing data B in B 3 And send to the printing module to print, so cycle until the blue tooth module does not receive the printing data B in B for more than 2s n Corresponding next print data B n+1 And judging that all the printing data in the step B are printed.
