Description
Technical field
The present invention relates to data processing field, more particularly to a kind of method and POS terminal of shared printing device.
Background technology
With developing rapidly for " internet+", many business using third-party application (such as Baidu takes out, Mobile banking)
Industry scene needs to print the document such as order and transaction voucher.With the increase of portfolio, and the facilitation of transaction, shop gradually
The mobile phone of waiter etc. needs to install mutually in requisition for the application program of printing list evidence, based on prior art, needs in such a scenario
Prepare wireless printer (printer of the radio communication such as wifi or bluetooth) to be used to provide printing work(for the application program on mobile phone
Energy.
But there is the POS terminal that outfit carries printing function in general shop, shared if a solution can be provided
Printing device in POS terminal, existing resource can not only be made full use of, and save the cost input of wireless printer.
The content of the invention
The technical problems to be solved by the invention are：How printing device POS terminal built in is shared.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
The present invention provides a kind of method of shared printing device, including：
The first bluetooth equipment built in printing device and POS terminal built in POS terminal establishes communication connection；
The serial ports of first bluetooth equipment receives the first data；
First data are sent to the printing device；
The printing device prints first data.
The present invention also provides a kind of POS terminal, it is characterised in that including printing device, the first bluetooth equipment and one or
Multiple processors and memory；
The memory storage has program, and is configured to by one or more of computing device following steps：
Trigger the printing device and establish communication connection with first bluetooth equipment；
The serial ports for triggering first bluetooth equipment receives the first data；
First data are sent to the printing device；
Trigger the printing device and print first data.
The beneficial effects of the present invention are：Prior art is different from, in the printing device and POS terminal built in POS terminal
The bluetooth equipment put is without communication connection, and the printing device built in POS terminal can not be shared by other external equipments, and the present invention is logical
The bluetooth equipment built in connection POS terminal and the printing device built in POS terminal are crossed, and bluetooth equipment is passed through into serial communication side
The external data that formula is got is forwarded to printer, so as to realize that the printing device built in POS terminal can be by with Bluetooth communication
The external equipment of function is shared without threshold, and existing POS terminal is upgraded to the smart machine for integrating blue-tooth printer, had
Beneficial to resource utilization is improved, hardware cost is saved.In addition, on the market connect blue-tooth printer application program be substantially it is logical
The serial communication mode for crossing bluetooth sends data to be printed, and other business datums of POS terminal can typically pass through bluetooth equipment
Other communication modes, for example file transmission, media play etc. carry out data transmission；Therefore, mode provided by the invention is passed through
Printing device built in shared POS terminal does not interfere with the business function of POS terminal in itself not only, and in shared POS terminal
The transformation of hardware or software need not be carried out by putting the external equipment of printing device, very convenient.
