In this embodiment, in particular, in the page printing mode, the printer is configured with a buffer with a large capacity, the printing content is divided into a plurality of pages, the data of each page is packaged into a packet for processing, the printer temporarily stores the received data in the buffer until the data of one page is received, and then the data printing of one page is executed.
S102, receiving the data to be printed in the buffer area character by character, typesetting on a printable logic area preset on a current page, abandoning the characters which are not received in the buffer area when judging that the whole occupied area of the characters on the printable logic area is about to exceed the printable logic area, and generating the typesetting of the printed page.
S103, printing the current page according to the layout of the printed pages.
In this embodiment, before printing, print setting parameters, including a print start position, a page print direction, a print page range, a printable logic area, print effect settings (such as format, watermark, rendering), and the like, need to be obtained, which is not specifically limited in the present invention.
As shown in fig. 2, the page printing direction may be from left to right, from bottom to top, from right to left, or from top to bottom, etc.
In this embodiment, the printable logical area may be preset, and includes a printable logical width and a printable logical height, which are printable boundary ranges generated according to the size of the current page. After the printing medium of the printer is replaced, the printable logic area matched with the printing medium can be correspondingly set, so that in each printing process, character boundary judgment is carried out according to the preset printable logic area, and the data to be printed is typeset on the printable logic area and then printed to obtain the current page.
In this embodiment, when it is determined that the entire occupied area of the characters on the printable logical area is about to exceed the printable logical area, the characters not received in the buffer area need to be discarded, so as to ensure that the number of characters received by one page of data to be printed is within the range of the printable logical area, and the overlapping printing situation does not occur.
In conclusion, in the process of receiving the data to be printed, the data obtained from the buffer are typeset on the printable logic area, when the whole occupied area of the characters on the printable logic area is judged to exceed the printable logic area, the characters which are not received in the buffer are abandoned, the pre-filling position of the characters can be judged, the data which can be accommodated in the current page can be accurately judged, and the overlapped printing is avoided.

s1025, judging whether the second preset position longitudinally exceeds the boundary of the printable logic area;
if not, setting the dot matrix data at a second preset position;
if yes, discarding the currently received characters and the characters which are not received in the buffer area to generate the printing page layout.
In this embodiment, when typesetting the currently received character on the printable logic area preset on the current page, it needs to sequentially determine whether the typesetting position of the currently received character will exceed the printable logic width D and the printable logic height H of the printable logic area. Wherein the boundary determination may be performed by calculating coordinates of a preset position of the currently received character on the printable logical area.
Specifically, referring to fig. 2, a first preset position of the current dot matrix data corresponding to the currently received character in the current row of the printable logic area may be obtained according to the coordinates of the previous dot matrix data. For example, assume the last latticeThe coordinates of the data are (x)0，y0) The coordinate of the first preset position of the currently received character is (x)1，y1) The abscissa value x of said first preset position1The abscissa value x of the last dot matrix data0Increasing a character width dx, the ordinate value y of the first preset position1Is the ordinate value y of the last dot matrix data0。
When x is1<D (i.e., the preset printable logical width), typesetting may continue on the current line. When the coordinate value x of the first preset position1And when the position is more than or equal to D, adjusting the placement position of the dot matrix data to the head of the next line to obtain a second preset position. Wherein, the abscissa value x of the second preset position2A head coordinate value set for the page, and a longitudinal coordinate value y of the first preset position2Is the ordinate value y of the last dot matrix data0One character length dy is added.
When the coordinate value y of the second preset position2<H (i.e. the preset printable logical length), the typesetting may continue in the next line, and the data to be printed in the buffer area continues to be received character by character. When the coordinate value y of the second preset position2And when the current received character and the character which is not received in the buffer area are not less than H, discarding the currently received character and the character which is not received in the buffer area so as to generate the printing page layout.
