The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
Fig. 1 is a schematic flow chart of a method for continuously printing single sheets according to an embodiment of the present application.
As shown in fig. 1, a method for continuously printing single sheets of paper in an embodiment of the present application specifically includes the following steps: s110 to S150.
S110, at least first page printing information is acquired.
The first page print information, and second page print information described below, each correspond to a page of the print medium. Each page of printing information corresponds to a plurality of times of transverse movement of the printing head, wherein one transverse movement is that the printing head moves from the leftmost side to the rightmost side of the printing medium or moves from the rightmost side to the leftmost side, and one transverse movement is recorded as a work cycle.
S120, controlling the printing head to work according to the first page printing information;
s130, acquiring at least second page printing information in the working process of the printing head;
s140, dynamically combining the second page printing information with the first printing information;
and S150, controlling the printing head to work according to the combined printing information.
The previously separated, relatively independent, pages of print information are combined using software code programming techniques to enable continuous control of printhead operation. The printing of one page of paper is not required to be finished first, then the printing of the second page of paper is not required to be carried out, and the last movement period of the first page of paper and the first movement period of the second page of paper are overlapped.
In the conventional printing technology, if the printing width of the printing head is A and the printing length of one page of paper is B, the printing head is required to go through four movement cycles per page of paper, wherein A multiplied by n is more than or equal to B and more than or equal to A multiplied by (n-1). In the last movement period, the printing head is in a non-full-load state, so that resource waste is caused, and the printing efficiency is influenced. For example:
the printing width of the printing head 1 is 100, the printing length of one page is 320, and according to the printing principle, the printing head 1 is required to go through four working cycles to complete the printing of one page. If the first sheet 2 and the second sheet 3 are printed continuously, eight job cycles need to pass. As shown in fig. 2.
The effective printing width of the print head 1 during the last movement cycle of the first sheet is only 20. The continuous printing method provided by the invention can effectively utilize the residual 80, thereby effectively improving the efficiency of continuous printing.
As shown in fig. 3, in the fourth movement period of the print head 1, the end portion of the first sheet 2 and the start portion of the second sheet 3 are printed simultaneously. Two pages are printed continuously, seven movement periods are needed, and one movement period is saved compared with the traditional printing technology. If three pages are printed in succession, the conventional printing technique requires twelve movement cycles, whereas the printing technique provided by the present invention requires only ten movement cycles. Therefore, the printing efficiency can be greatly improved.
Further, dynamic merging may be implemented by:
after first page printing information is acquired, splitting the first page printing information into a plurality of strip-shaped data; wherein, one strip data corresponds to one working period of the printing nozzle;
controlling the operation of the printing nozzle according to the strip data split from the first page of printing information;
acquiring second page printing information while the printing head works;
determining first strip-shaped data of second page printing information according to the residual space of the last strip-shaped data of the first page printing information;
merging the last strip data of the first page printing information, the preset page interval data L and the first strip data of the second page printing information into strip data;
controlling the printing head to work according to the combined strip data;
splitting the rest part of the second page of printing information into a plurality of strips of strip-shaped data;
the print head job is controlled based on the strip data into which the remaining portion of the second page of print information is split.
In addition, dynamic merging can be realized in another way:
the method comprises the steps of firstly acquiring all or part of content of first page printing information, and sequentially intercepting printing data with a certain printing length from the beginning of the first page printing information as strip-shaped data, wherein the printing length is the effective printing width of a printing head. And controlling the printing head to work periodically according to the intercepted strip data. The printing work of the printing head and the printing information intercepting work are synchronously carried out. When the last part of the first page of printing information is intercepted, if the remaining part of the first page of printing information is not enough to be the length of one piece of strip-shaped data, certain printing information is acquired from the beginning part of the second page of printing information to complement the length of the strip-shaped data.
For example:
there are 100 lines of print information per page, the print head completes 30 lines of job per cycle, and the preset page pitch data is 4 lines.
Firstly, intercepting the first 30 rows of the first page of printing information as first strip-shaped data, and controlling a printing head to finish a cycle of operation according to the first strip-shaped data; and intercepting the second strip data while the operation is performed in the previous period until the operation in the first three periods is completed. When 90 lines of information are intercepted, only 10 lines are left, and the printing length is insufficient, namely 30 lines, at the moment, the first 16 lines of the second page of printing data are taken, and the last 10 lines of the first page of printing information, the gap data 4 lines and the first 16 lines of the first page of printing information are combined into a complete piece of printing data;
the remaining 84 lines of the second page of print information continue to be divided into 30, 24.
If the third page of printing data is involved, the final part of the second page of printing information is merged with the beginning part of the third page by using the same principle, and finally continuous printing is realized. That is, the last 24 lines of the second page of print information, plus the gap data 4 lines and the first 4 pages of the third page, form a strip of data
In some embodiments, the print information includes text data, i.e., print content, and page size data, including page width, length of print. The start and end positions of the print head are controlled by the page width.
Fig. 4 is a schematic diagram of a process of continuously printing two sheets with different page widths in the printing method provided by the present invention. The printing width of the first paper is a, the printing width of the second paper is b, and a is less than b.
As shown in FIG. 4, the initial position of the print head is controlled based on the printing width a in the 1 st to 3 rd movement periods of the print head. In the 4 th movement cycle of the print head, the first and second sheets are crossed, the starting position of the print head is controlled with a larger width value, i.e. b.
The printing method can continuously print paper with different widths without repeated mechanical reset, reduces the determination times of the printing position and is beneficial to improving the printing efficiency.
In the process of conveying the sheet of material to a printing position, the field programmable gate array logic chip controls the servo motor to move through the numerical value of the high-precision rotary encoder, so that the accuracy of the length of the sheet of material is ensured, and after the conveying length of the sheet of material is reached, the field programmable gate array logic chip needs to start to control the servo motor to transmit the next sheet of material according to the state of the current detection sensor; the ink-jet printing action of the sheet material and the conveying action of the next sheet material are completed at the same time, so that the material conveying speed can be the highest.
Before the tail part of the ink-jet printing of the sheet of material enters the printing position, the field programmable gate array logic chip needs to ensure that the distance between the head part of the next sheet of material and the tail part of the sheet of material is a preset length distance through control logic, and the tail part of the sheet of material and the head part of the next sheet of material are conveyed to the printing position together on the premise of ensuring that the distance between the two sheets of material is fixed, so that the combined ink-jet printing of the two adjacent sheets of material is completed.
Although the present application is disclosed above, the present application is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the scope or spirit of the present disclosure, and it is intended that the scope of the present disclosure be defined by the appended claims.
