Print data and unprinted print data into flash memory device output storage.
Reference picture 3 simultaneously combines Fig. 2, and the Method of printing of thermal printer includes self-test step S1, backup-step S2, printing step
Rapid S3 and fault handling steps S4.
Self-test step S1 includes：The state of thermal printer is detected, and feedback states signal, i.e. thermal printer
The state of itself is detected, such as remaining printing paper amount, motor conditions, heat-sensitive sheet situation, driving situation and each inspection paper pass
The situation of sensor.
If status signal is normal state signal, then printing step S3 and backup-step S2 is performed.
If status signal is fault status signal, then fault handling steps S4 is performed, contact pilotage processing step S4 includes：
First, thermal printer receives print data；
Then, for thermal printer by communication unit forwarding print data to thermal printer is backed up, backup printer can
Think more, as long as being connected with the printer of the thermal printer networking of the failure, a transmission print data can be selected, beaten
Print.
Then, backup thermal printer prints to print data；
Finally, after backup thermal-sensitive printer printing, printing finished signal is fed back to former thermal printer, then pass through original
Thermal printer feeds back to intelligent terminal.
Reference picture 4 simultaneously combines Fig. 2, and Fig. 4 is the flow chart of print data backup method.The print data of thermal printer is standby
Part method includes printing step S3 and backup-step S2.
Printing step includes：
Step S31, intelligent terminal 11 or cloud platform 16 export printing number by the heat sensitive printer 13 of communication module 136
According to print data is the printer instructions collection for controlling printer, and thermal printer 13 receives the print data.
Step S32, processor are parsed to print data and generate view data, it is preferable that thermal printer is fought each other
Printing is according to the view data for after parsing being generation bmp forms.
Step S33, subsequent heat-sensitive sheet and rubber roll obtain print trigger signal, and rubber roll then carries out rotation paper feed, and heat-sensitive sheet
Paper feed action is then coordinated to carry out image printing on printing paper according to view data；
Step S34, judge whether that printing finishes, such as printing does not finish, then return to step S31 continues to print number
According to, as printing finish, then export printing finished signal.
Step S35, thermal printer obtain printing finished signal, complete printing step.
Step S36, after printing finished signal is obtained, thermal printer also exports cut paper signal, driving to cutter
Cutting knife carries out cut paper action to document, then exports the document 137 of printing.
At the same time, backup-step is also with then printing step while performed, and backup-step includes：
Step S21, after step S32, i.e., when print trigger signal triggers, obtain bmp format picture datas and be used to back up
Processing.
Step S22, when there is multistage print data, then the bmp format picture datas after multiple parsings is received successively, and
Multiple images data are spliced, reference picture 4, during splicing, a newly-built bmp tile data, subsequent basis from top to down
The view data received is placed, and before no triggering printing finished signal, is constantly spliced and combined in order, when
When printing finished signal triggers, spliced view data preserves the backup file into bmp forms, and as electronics counterfoil 132
Preserve in memory.
When performing above-mentioned printing step, such as there is print fault, such as paperboard, lack paper or other failures, then processor meeting
Fault-signal is received, then, unprinted print data is forwarded to backup thermal printer by processor, by backing up temperature-sensitive
Printer continues to print.
Therefore because electronics counterfoil is that necessarily possess visual particular/special requirement, therefore merely can not will print number
Preserved according to ground, because print data is typically the instruction set of printer matching, do not possess visuality, instruction set be merely able to by
Printer identifies, so being to need to be preserved in the pattern of the actual document actually printed, just electronics counterfoil can so had
Standby authenticity, legitimacy and integrality, therefore the figure that this case is used to be imaged by when print trigger signal triggers, obtaining heat-sensitive sheet
As data, and when printing finished signal triggers, view data, which with picture format preserve, turns into backup file, backup text
Part and printing conformity of document, carrying out preservation by pictorial manner easily can be transmitted and consult, it possess authenticity,
Legitimacy and integrality.When printing the print data of segmented, view data can be obtained successively, and performs the splicing of image,
Then in printing finished signal or cut paper action triggers, spliced image is saved as into backup file.Using bmp forms text
Part is handled and preserved, and its image is the demand for being closer to printer dot lattice printing, is more adapted to the printing with instruction set
Data mutually convert, and bmp formatted files compression ratio is high, are also more adapted to the demand of network transmission.
Meanwhile when thermal printer breaks down, complete print data can be forwarded to backup by communication unit
On thermal printer, or unprinted print data can be forwarded on backup thermal printer by communication unit, makes backup
Printer continues to print, and user no longer needs to reconnect, or reselects, and breaks down and forwards number automatically by thermal printer
According to, after printing by feedback tell user, Consumer's Experience is greatly provided.
In addition, by setting sound module on thermal printer so that thermal printer be no longer rely on computer and with electricity
The audio amplifier sounding of brain connection, thermal printer can be prompted automatically when printing finishes, lacks paper, failure and alarm, convenient
User knows the state of printer.
And the real-time monitoring by power management module, when there is power down, using the of short duration power supply of energy-storage module,
Then processor is allowed to enter the pattern of power down protection, in protected mode, processor is stored by data interface module to mobile
Print data and unprinted print data in device output storage, user can be by the printing numbers on flash memory device
Printed according to transfer, it is convenient for users to use.
Furthermore it is that the first communication unit uses as normal communication and on the wide area network with extraneous connecting communication, and the
Two communication units are connected by secure communication circuit with internal server so that print data or backup number on thermal printer
Connected according to without only relying on a communication module to be communicated with the external world, but secrecy transmission is carried out by independent communication circuit, increased
The confidentiality of addend evidence.
