Print data is converted into picture or text, takes out keyword by print instruction, generates parsing by the format that MAC Address adds timestamp
Print data file afterwards generates superadd-print data file according to the content to be pursued and attacked, by the print data text after parsing
Part and superadd-print data file print and/or are shown as a complete bill, set wherein pursuing and attacking information and being located in the bill
Fixed pursues and attacks region.
9. print data bridge system as described in claim 1, it is characterised in that carried out according to following manner control printer
Pursue and attack the printing or display of information: according to content before the tail of print data file printing or display raw billing files, foundation is beaten
Printing or display position of the information in bill are pursued and attacked in print configuration determination, when pursuing and attacking printing or display position of the information in bill
When to be inserted in front of the tail of raw billing files between content and bill tail, according to superadd-print data file in raw billing files
Tail before pursue and attack or show print data behind content, pursuing and attacking printing or display information behind according to print data file
The bill tail of raw billing files；It is the bill in raw billing files when pursuing and attacking printing or display position of the information in bill
When behind tail, the bill tail of raw billing files, foundation are printed or shown behind content before the tail of raw billing files
Print data file prints the bill tail of raw billing files before the tail of raw billing files behind content, beat according to addition
Print data file, which is printed or shown behind the bill tail of raw billing files, pursues and attacks information.
10. print data bridge system as described in claim 1, it is characterised in that the FPGA can use following work side
Formula:
Step S1. is communicated with POS machine foundation；
Step S2. is communicated with printer foundation；
Step S3. receives the configuration whether ARM needs to carry out the printer data of POS superadd-print, if necessary to additional,
S4 is entered step, S5 is otherwise entered step；
Step S4. superadd-print data are isolated printer data, are sentenced to printer data to the POS terminal data received
Break end tail, when being matched to rostral-caudal mark, carries out data by the way of to separated transmission partial data response NAK and cuts
It is disconnected, it waits ARM to send the print data for needing superadd-print, after the print data for receiving superadd-print, these is printed into number
According to transmitting to printer, waits ARM to send additional end mark and exited after receiving the addition end mark that ARM is sent
Additional mode, enters step S5；
Step S5. forwarding printer data isolates printer data to the POS terminal data received, beats what is isolated
Print machine data are transmitted directly to printer, keep POS and printer communication,
Step S3-S5 is repeated, until printing terminates.
