Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Please refer to fig. 1, which is a flow chart of a method for recovering a lost word stock of a thermal printer according to the present invention;
the method for recovering the lost word stock of the thermal printer comprises the thermal printer and an application module which are connected and are both included in an intelligent POS terminal, wherein the thermal printer comprises a thermal printer word stock, the application module comprises an application module word stock, and the application module word stock is stored in a read-only memory of the application module word stock.
The word stock quantity of the application module word stock is larger than that of the thermal printer word stock, the thermal printer word stock is provided by a thermal printer manufacturer, the application module word stock comprises the thermal printer word stock and other word stocks compatible with the thermal printer, and when the thermal printer word stock needs to be burnt into other compatible word stocks in the application module word stock, the application module can be burnt in.
The method for recovering the lost word stock of the thermal printer comprises the following steps:
s1, detecting the first font information lost in the generated thermal printer font;
and when the thermal printer normally operates, the word stock is loaded from the thermal printer word stock for printing, so that the printing efficiency is facilitated.
The thermal printer detects whether the word stock is lost, can perform daily detection on the thermal printer, and can also perform detection when the thermal printer is abnormal in printing.
In the embodiment of the present invention, the occurrence of an abnormality in the printing process of the thermal printer is described. The method comprises the steps that when the thermal printer stops printing in the printing process, the thermal printer detects the reason causing the stop of printing, if the printer detects that the printer is a lost character library, on one hand, a user is prompted to be the lost character library through an interactive interface of an application module, on the other hand, the thermal printer searches and retrieves the lost information of the character library, for example, the reason that the character library is lost is searched, whether the character library is provided with a name for replacing, completing printing and retrieving the lost character library is searched, the name of the lost character library is a uniform name in the industry field, and the name of the lost character library can also be a name named by a manufacturer of the thermal printer.
And according to the searched and retrieved information, when judging that external recovery is needed, generating first font library information from the searched and retrieved information, wherein the first font library information at least comprises the memory size of the lost font library packet, a storage path, the name of the lost font library, and an example of the font library.
S2, the CPU in the application module acquires the lost first font information of the thermal printer;
the central processing unit is included in the application module and acquires first font information lost by the thermal printer through connection with the thermal printer.
The read-write memory in the S3 application module processes according to the instruction of the central processing unit, matches the lost first font library information, and matches the second font library information;
the read-write memory is included in the application module and connected with the central processing unit and the read-only memory. The central processing unit sends an operation instruction to the read-write memory according to the received first word stock information, the read-write memory is instructed to match the first word stock information, the read-write memory extracts key information from the first word stock information, such as extracting the name of a lost word stock, and then searches and matches an application module word stock in the read-only memory according to the key information of the first word stock information, and if the same word stock name is searched according to the word stock name in the first word stock information, second word stock information is generated through matching; if the same word stock name is not searched, searching a word stock compatible with the thermal printer and similar to the type of the word stock, matching to generate second word stock information, and transmitting the second word stock information to the thermal printer to judge whether the second word stock information conforms to the thermal printer. The second font library information generated by matching comprises the first font library information, a matched font library storage path and a matched font library packet, namely the information amount of the second font library is greater than that of the first font library.
S4, loading the lost second font information from the read-only memory to the thermal printer font;
and when the thermal printer judges that the second word stock information conforms to the first word stock information, the central processing unit receives an instruction of loading the second word stock information from the thermal printer, the central processing unit sends the instruction of loading the second word stock information to the read-write memory, and the read-write memory loads the second word stock information from the read-only memory.
And the mode of loading the second word stock information from the read-only memory is copying, and the copied content is a matched word stock packet.
Referring to fig. 2 and 3 together, fig. 2 is a block diagram illustrating a structure of a lost word stock recovery terminal of a thermal printer according to the present invention; fig. 3 is a schematic structural diagram of a thermal printer missing word stock recovery terminal provided by the invention.
