Abstract

An image printing method and printer is provided. The method comprises obtaining an original data file of an image to be printed from a database; dividing the original data file into a plurality of first data files and storing the first data files in a plurality of first memory blocks correspondingly; receiving an image printing request, the image printing request carrying first position information of the image to be printed; determining from its position information of the image to be printed second position information contained in the first position information, and filling a first data file corresponding to the second position information to a second memory block from the first memory block where the first data file is located through memory mapping mechanism to form a second data file to be printed; and printing and outputting the second data file in the second memory block.

Claims

1. An image printing method characterized in comprising:

obtaining an original data file of an image to be printed from a database;

according to a size of the original data file, dividing the original data file into a plurality of first data files and storing the first data files in a plurality of first memory blocks correspondingly;

receiving an image printing request, the image printing request carrying first position information of the image to be printed;

for each first data file among the plurality of first data files, determining from its position information of the image to be printed second position information contained in the first position information, and filling a first data file corresponding to the second position information to a second memory block from the first memory block where the first data file is located through memory mapping mechanism to form a second data file to be printed; and

printing and outputting the second data file in the second memory block.

2. The method of claim 1, characterized in that, according to the size of the original data file, dividing the original data file into the plurality of first data files comprises:

according to the size of the original data file and the size of the first memory block, dividing the original data file into the plurality of first data files, the size of each of the first data files being the same as the size of the first memory block.

3. The method of claim 1, characterized in that, before obtaining the original data file of the image to be printed from the database, further comprising:

obtaining a third data file of the image to be printed; and

screening the third data file to generate the original data file of the image to be printed and storing it in the database.

4. The method of claim 3, characterized in that after receiving the image printing request, further comprising:

creating the second memory block, the size of the second memory block being the same as that of the original data file corresponding to the first position information of the image to be printed carried in the image printing request.

5. The method of claim 4, characterized in that the position information of the image to be printed comprises coordinates of upper left corners of rectangular images in the image to be printed and lengths and widths of the rectangular images.

6. A printer, characterized in comprising:

an acquisition module, a division module, a reception module, a mapping module and a printing module, wherein,

the acquisition module is configured to obtain an original data file of an image to be printed from a database;

the division module is configured to, according to a size of the original data file, divide the original data file into a plurality of first data files and store the first data files in a plurality of first memory blocks correspondingly;

the reception module is configured to receive an image printing request, the image printing request carrying first position information of the image to be printed;

the mapping module is configured to, for each first data file among the plurality of first data files, determine from its position information of the image to be printed second position information contained in the first position information, and fill a first data file corresponding to the second position information to a second memory block from the first memory block where the first data file is located through memory mapping mechanism to form a second data file to be printed;

the printing module is configured to print and output the second data file in the second memory block.

7. The printer of claim 6, characterized in that the division module is particularly configured to, according to the size of the original data file and the size of the first memory block, divide the original data file into the plurality of first data files, the size of each of the first data files being the same as the size of the first memory block.

8. The printer of claim 6, characterized in that the acquisition module is further configured to

obtain a third data file of the image to be printed;

and

screen the third data file to generate the original data file of the image to be printed and store it in the database.

9. The printer of claim 8, characterized in further comprising:

a creation module, configured to create the second memory block, the size of the second memory block being the same as that of the original data file corresponding to the first position information of the image to be printed carried in the image printing request.

10. The printer of claim 9, characterized in that the position information of the image to be printed comprises coordinates of upper left corners of rectangular images in the image to be printed and lengths and widths of the rectangular images.
