[ METHOD EMBODIMENT 9 ]
The data printing method provided in the present embodiment is described below by taking a bluetooth printing apparatus as an example (although the present invention is not limited thereto, and a person skilled in the art may use a Wi-Fi (Wireless-Fidelity) printing apparatus or a GPRS (General packet radio Service) printing apparatus according to actual needs). The method comprises the following steps:
treatment 1: searching for a Bluetooth device, identifying a printing apparatus from the searched Bluetooth devices, and adding the identified printing apparatus to a printer connectable queue. Specifically, the following method can be adopted to identify whether the bluetooth device is a printing apparatus:
treatment 1.1: whether the device name of the bluetooth device contains a keyword (for example, "print" or the like) is identified, if so, processing 1.3 is executed, and if not, processing 1.2 is executed.
Treatment 1.2: an Identifier (ID) for identifying the bluetooth device belongs to a set of identifiers (the identifiers in the set may be provided by a printer manufacturer), and if so, the bluetooth device is determined to be a printing apparatus, and if not, the bluetooth device is determined not to be a printing apparatus.
Treatment 1.3: and identifying whether the Bluetooth equipment supports the writing operation, if so, judging that the Bluetooth equipment is a printing device, and if not, judging that the Bluetooth equipment is not the printing device.
And (3) treatment 2: the printing device is connected.
In the present embodiment, the printing apparatus can be connected in two ways:
(1) connecting a printing device according to the clicking behavior of the user;
(2) the printing device is automatically connected.
With respect to the method (1), as shown in fig. 10, in the case where bluetooth is already on, when the user enters a specified page (for example, a "printing apparatus setting" page), the request side of data printing performs the following processing: searching for connectable wireless communication devices; identifying a printing apparatus (e.g., printer 1, printer 2, and printer 3 in fig. 10) from the searched wireless communication apparatuses; and displaying the identified printing device to the user. The user clicks on the printing apparatus to be connected. The request end of the data printing sends a connection request to the printing device in response to the click behavior of the user.
With respect to the mode (2), in the related art, in order to achieve the connection purpose, if the connection is not successful, the search and the automatic connection operation of the printing apparatus are continuously tried. However, this approach is extremely wasteful of system resources and impacts application performance. In the present embodiment, once the automatic connection fails, the connection request is not repeatedly sent, so as to avoid excessive consumption of system resources and influence on application performance.
Further, in the present embodiment, with respect to the mode (2), it is also possible to automatically connect the printing apparatus in response to a designation request (for example, a request to acquire a printer setting page, or a request to process an order), exemplarily, if an order processing request is received, the printing apparatus is automatically connected for a demand to print an order. Therefore, the automatic connection of the printing device can be triggered in combination with the scene, so that the system resource is further saved, and the influence on the application performance is reduced.
Further, after connecting a certain printing apparatus, the user may disconnect the printing apparatus and connect another printing apparatus.
And (3) treatment: the print data is preprocessed.
Such pre-treatments include, for example, but are not limited to: adding separators to the print data according to the print requirements, the effect of which is shown in fig. 11; and, in the case where the print data contains sensitive data, performing encryption processing on the print data. In this embodiment, the same scheme as that of method embodiment 4 is used to identify sensitive data and encrypt print data, which is not described herein again.
And (4) treatment: according to the set command conversion rule, the preprocessed print data is converted into a general standard command (for example, ESC command) recognizable by the printing apparatus, and the effect is shown in fig. 12.
And (4) treatment 5: and storing the converted general standard instruction in a printing data storage area.
And (6) treatment: the converted universal standard instruction is read from the print data storage area and sent to the printing apparatus so that the printing apparatus performs the data printing process according to the received universal standard instruction.
For example, the converted general-purpose standard commands may be sent to the printing apparatus one by one, or all of the converted general-purpose standard commands may be sent to the printing apparatus at once.
