Abstract
The invention provides a method for implanting information into printing data. The method needs to be provided with an MCU (microprogrammed control unit), an RAM (random access memory) and a nonvolatile storage device and includes firstly, monitoring a printing peripheral interface of an upper computer in real time through the MCU; secondly, when the printing data is issued by the upper machine and monitored by the MCU, storing the print data into the buffer area inside the RAM; thirdly, when the printing data inside the buffer area reaches a complete data packet, reading implantation information from the nonvolatile storage device; fourthly, after the MCU packages the implantation information and the complete data packet of the upper computer, sending the packaged data to a printer through the printing peripheral interface of the printer; and lastly, printing the received packaged data through the printer. When applied to the field of receipt advertising, the method for implanting the information into the printing data can save the cost of back color printing, achieve small-quantity retail and be compatible with printers and printing paper of different specifications. Besides, the method for implanting the information into the printing data is not affected by software systems, so the compatibility is improved, the software development cost is saved and the large-scale network management can be achieved.
Description
Technical field
The present invention relates to a kind of Design of Digital Circuit, embedded system technology field, relate in particular to a kind of method of in print data, implanting information.
Background technology
Billing information advertisement on the market at present mainly contains two kinds of patterns: preprint brush and the software control formula.
Preprint brush---refer to by batch color printing, in advance in the advertisement of receipt paper roll back up.It is as follows to preprint brush shortcoming:
The input threshold is higher, owing to adopt back up mode in advance, must just can send to press more than several thousand volumes at every turn, about 10 yuan of every volume printing cost, namely throwing in an advertisement needs 30,000 yuan of (3000 volume meter) advertisements can only be imprinted on the receipt back side at least, the user turns a blind eye to substantially, and to throw in the place single, only limits to the printer that the minority supermarket can not compatible different paper specification at present.
The software control formula---refer to by the cash register software control, generate advertisement automatically at every receipt afterbody.Its shortcoming is as follows: restricted by various cash register systems and the software compatibility; can only use in some inside, supermarkets, the cost of development height, medium and small supermarket and conventional store can't be born; can't form networked scale specialized operation, only have the big supermarket of only a few to manage voluntarily.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method of implanting information in print data, and it has saved the color printing cost, can realize retail in a small amount, can compatible different size printer and printer paper.
The present invention is achieved in that
Scheme one:
A kind of method of in print data, implanting information, described method need provide a MCU, a random access memory and a non-volatile memory device, and this method specifically comprises the steps:
Step 1, by MCU the printing Peripheral Interface of one host computer is monitored in real time;
Step 2, issue print data when host computer, when MCU has monitored print data, print data is stored in the random access memory in the buffer area;
Step 3, after the print data in the buffer area reaches complete packet, from described non-volatile memory device, read the information that will implant;
After the information that step 4, MCU will implant and the complete packet of host computer were packed, the printing Peripheral Interface by printer sent to printer;
Step 5, printer interface receive that the data of packing print.
Scheme two:
A kind of method of in print data, implanting information, described method need provide a MCU, a random access memory and a non-volatile memory device, and this method specifically comprises the steps:
Step 10, by MCU the printing Peripheral Interface of one host computer is monitored in real time;
Step 20, issue print data when host computer, when MCU has monitored print data, print data is stored in the random access memory in the buffer area;
Step 30, after the print data in the buffer area reaches complete packet, the printing Peripheral Interface of packet by printer sent to printer prints;
Step 40, when MCU monitor described packet print finish after, from described non-volatile memory device, read the information that will implant;
Step 50, the information that will the implant printing Peripheral Interface by printer sends to printer and prints.
The present invention has following advantage: the present invention adopts microcontroller as handling core, and the mode of repacking again by the intercepting print data stream realizes the implantation of billing information.At first the carrying out of the printing Peripheral Interface of the host computer of MCU monitored in real time, when having monitored data, data are carried out buffer memory, after receiving complete packet, in non-volatile memory device, read information to be implanted, this information and the host computer data that receive are packed together, send to printer by another printing Peripheral Interface that links to each other with printer, print list by printer.The present invention and traditional brush contrast, advantage: saved the color printing cost preprinted; Can realize retail in a small amount; Advertisement improves view rate in the front; Can compatible different size printer and printer paper.The present invention and the contrast of traditional software control formula, advantage: not influenced by software systems, compatibility is improved; Saved software development cost; Can realize the large scale network operation.

Embodiment
See also illustrated in figures 1 and 2ly, a preferable scheme of the present invention is: a kind of method of in print data, implanting information, and described method need provide a MCU, a random access memory and a non-volatile memory device, and this method specifically comprises the steps:
Step 1, at first be each hardware of first initialization, by MCU the printing Peripheral Interface of one host computer monitored in real time; This described host computer is PC or cashier's machine;
Step 2, issue print data when host computer, when MCU has monitored print data, print data is stored in the random access memory in the buffer area;
Step 3, after the print data in the buffer area reaches complete packet, from described non-volatile memory device, read the information that will implant;
After the information that step 4, MCU will implant and the complete packet of host computer were packed, the printing Peripheral Interface by printer sent to printer;
Step 5, printer interface receive that the data of packing print; Above-mentioned printing Peripheral Interface comprises: wave points such as parallel port, serial ports, USB, Ethernet interface and bluetooth; This print data is in the present invention based on the print data of bill.
In the present invention; the judgment mode that described print data reaches complete packet is: a time threshold value is set in MCU; after having monitored print data, MCU begins data are saved in buffer zone; begin to carry out timing by a timer after host computer stops to send data when monitoring; after the timing time of timer reaches described time threshold; the buffer zone of random access memory suspends buffer memory, and all print datas that then receive in this time threshold are complete packet.
