It during the present invention is implemented, describes for convenience, the present invention will print and printing is referred to as printing.The present invention is suitable for appointing
What plane printing, is not suitable for 3D printing.Secondary printing refers on the paper of existing printing or print content, is printed.Two
The content of secondary printing can first time printing reserved place on, can also in any specified position, can also with once beat
Print overlaps.
An embodiment of the present invention provides a kind of secondary printing alignment schemes, as shown in Figure 1, including：
101：Print initial content；
Printer to needing the content printed to print for the first time.Printing refers to printer and is beaten on the paper of blank for the first time
Print.Printing can reserve the vacancy of secondary printing for the first time, can not also reserve.For the content and form present invention printed for the first time
It does not limit.
102：Simultaneously sweep test prints content to part paper feed for the first time；
In secondary printing, the feeder of printer transmits a part for the paper of pending secondary printing into printer, and
The Some paper sheets for entering printer are scanned with scan module.It is how many to transmit into the part of printer, and the present invention is not done
It limits.The present invention provides two kinds of feasible mechanism methods.Method one, paper feed amount can be a specified length, such as 3 lis
Rice, 5.5 centimetres.Paper feed amount needs to ensure that scanner can scan and partly print content for the first time, so that control module will scan
To content and typesetting in content compared, calculate offset and rotation.Method two, paper feed are gradual, i.e. paper feeds
Device transmits paper into printer with certain speed, while scan module scans the communicated content into printer, by center
Control module judges whether to stop paper feed.For example, in instrument scanning to the first row printed for the first time partly or entirely printing to be scanned
Rong Shi, central control module calculate offset and the rotational correction for judging that scanning information has carried out secondary printing enough at this time,
It is then sent out to printer and stops paper feed signal.
103：Graphic Pattern Matching calculates offset and rotation, adjusts secondary printing content
