Description

Technical Field

[0001] The present invention relates to the field of printing technology, and in particular to a high-efficiency two-color printing method and a printer. Background Art

[0002] The printing method of the dot matrix printer is to drive the printing needle to hit the ribbon, transfer the ink on the ribbon to the printing paper to form a dot matrix output. It has unique carbon printing and continuous printing functions, which can easily print text, tables and images on printing paper, copy paper, certificates and envelopes. It is suitable for printing various professional reports, passbooks, invoices, cards and other output media. Common dot matrix printers are monochrome printing and cannot be used in red-headed documents, documents with red seals, special certificates and other application fields. The two-color printing function requires targeted design. The current two-color printing implementation method of the two-color dot matrix printer is to add a ribbon conversion structure, that is, a ribbon switching mechanism is provided on the carriage to control the relative position of the ribbon in the print head. The second is to make targeted changes to the print head structure. The common method is to remove the printing needle at the color boundary of the corresponding ribbon on the basis of the original print head, or to separate the printing needle to avoid the color boundary of the ribbon.

[0003] The color printing method of adding a ribbon conversion structure to the printer carriage requires additional conversion motors and related drive components. The overall structure is complex, the space requirement is large, and the product cost is increased. In addition, the ribbon position needs to be changed during printing, which affects the printing reliability.

[0004] At present, the printing data mode of the dot matrix printer is single-line processing, that is, the printer control system receives the printing data by line and sends it to the print head for printing output. When processing two-color printing, the color data is separated, and the color 1 data of the line is printed first, and then the color 2 data of the line is printed. The print pins of two colors cannot print at the same time.

[0005] For two-color printing that separates the print pins at both ends and avoids the intersection of different colors, the optimal structure is usually selected in which the print pin groups at both ends are half the printing height, ensuring that a row of dots corresponding to two colors is printed twice. When two color data exist in the same row, the printer needs to print 4 times, and the printing efficiency is low.

[0006] For the two-color printing method of removing some of the print pins from the print head, a part of the print pins is removed near the junction of different colors of the ribbon, and the two end print pin groups corresponding to the different color printing are separated with the junction of different colors of the ribbon as the center, corresponding to the two-color printing. Since the number of pins in the print head is less than that of a normal print head, the print pin group can only use a smaller number of print pins when printing, requiring more compensation printing times, and the printing efficiency is lower than that of the print pin separation type, which seriously affects the printing efficiency.

[0061] Specific examples include Figure 1 As shown, there are four lines of print data in total, and each line of print data belongs to two color areas, namely, the first color area and the second color area. The first color area is located on the left side of the second color area, and the first color area and the second color area have different colors. The first color area is a black area, and the second color area is a red area, that is, the data ACEG in the first color area is black, and the data BDFH in the second color area is red, N1 represents the first line AB, N2 represents the second line CD, N3 represents the third line EF, and N4 represents the fourth line GH.

[0062] Printing process Figure 2 The specific steps are described as follows:

[0063] Step S101: drive the second printing needle group located at the lower part of the print head to hit the red area on the ribbon, first print out the upper half B1 of the red B, and then print out the lower half B2 of the red B.

[0064] Step S102: Simultaneously drive the first print needle group located at the upper part of the print head and the second print needle group located at the lower part of the print head, so that the first print needle group hits the black area on the ribbon and the second print needle group hits the red area on the ribbon.

[0066] Step S104: Repeat the driving steps of the first printing needle group and the second printing needle group. The first printing needle group first prints out the upper half E1 of the black E, and the second printing needle group first prints out the upper half H1 of the red H. Then, the first printing needle group prints out the lower half E2 of the black E, and the second printing needle group prints out the lower half H2 of the red H.

[0067] Step S105: Repeat the first printing needle group driving step. The first printing needle group first prints out the upper half G1 of the black G, and then prints out the lower half G2 of the black G, and the printing is completed.

[0068] It should be noted that during the printing process of the first printing needle group and the second printing needle group, the paper feeding mechanism will perform a line feed operation on the printing carrier to avoid overlapping of the printing data on the printing carrier.

[0069] From the above printing steps, it can be concluded that when the print data is four lines, the print head prints ten times in total, the first line and the last line of the print data are printed twice more, and the middle line is printed twice (one line each for black and red), and the total number of prints is 2N+2, where N is the number of lines of the print data. Compared with other printing methods, when printing the same content, the above printing method significantly reduces the number of prints using the above printing method, and the printing efficiency is significantly improved.

[0070] In some embodiments of the present application, if the first color area and the second color area have the same color, and each line in the print data includes data belonging to the first color area and data belonging to the second color area, the printing method is as follows:

[0071] The first printing needle group is driven to impact the first color area and the second color area on the ribbon to print the Nth i The upper half of the row's data; and,

[0072] The second printing needle group is driven to hit the first color area and the second color area on the ribbon to print the Nth color of the first color and the second color. i+1 The upper half of the row's data;

[0073] The first printing needle group is driven to impact the first color area and the second color area on the ribbon to print the Nth iThe lower half of the row's data; and,

[0074] The second printing needle group is driven to hit the first color area and the second color area on the ribbon to print the Nth color of the first color and the second color. i+1 The lower half of the row's data;

[0075] When the number of lines of printed data is an odd number;

[0076] driving the first printing pin group to hit the first color area and the second color area on the ribbon to print out the upper half of the data of the last line of the odd-numbered lines belonging to the first color area and the second color area; and,

[0077] The first printing needle group is driven to hit the first color area and the second color area on the ribbon to print out the lower half of the data of the last line of the odd-numbered lines belonging to the first color area and the second color area.

[0078] Specific examples include Figure 3 As shown, there are five lines of printed data in total, and each line of printed data belongs to two color areas, namely, the first color area and the second color area. The first color area is located on the left side of the second color area, and the first color area and the second color area have the same color. The first color area and the second color area are both black areas or red areas, that is, the data ACEGI in the first color area and the data BDFHJ in the second color area are both black or red, N1 represents the first line AB, N2 represents the second line CD, N3 represents the third line EF, N4 represents the fourth line GH, and N5 represents the fifth line IJ.

[0079] Printing process Figure 4 The specific steps are described as follows:

[0080] Step S201: Simultaneously drive the first print pin group located at the upper part of the print head and the second print pin group located at the lower part of the print head, so that the first print pin group hits the first color area and the second color area on the ribbon, and the second print pin group hits the first color area and the second color area on the ribbon, and the first print pin group prints out the upper half A1B1 of the first line AB, and the second print pin group prints out the upper half C1D1 of the second line CD, and then, the first print pin group prints out the lower half A2B2 of the first line AB, and the second print pin group prints out the lower half C2D2 of the second line CD.

[0081] Step S202: Repeat the driving steps of the first printing needle group and the second printing needle group. The first printing needle group prints out the upper half E1F1 of the third line EF, and the second printing needle group prints out the upper half G1H1 of the fourth line GH. Then, the first printing needle group prints out the lower half E2F2 of the third line EF, and the second printing needle group prints out the lower half G2H2 of the fourth line GH.

[0082] Step S203: Repeat the first printing needle group driving step. The first printing needle group first prints the upper half I1J1 of the fifth line IJ, and then prints the lower half I2J2 of the fifth line IJ, and the printing is completed.

[0083] It should be noted that during the printing process of the first printing needle group and the second printing needle group, the paper feeding mechanism will perform a line feed operation on the printing carrier to avoid overlapping of the printing data on the printing carrier.

[0084] From the above printing steps, it can be concluded that when the print data is four lines, the print head prints four times in total; when the print data is five lines, the print head prints six times in total. It can be seen that when the print data is monochrome, if the number of lines N of the print data is an even number, the number of prints is N; if the number of lines N of the print data is an odd number, the number of prints is N+1. Compared with other printing methods, when printing the same content, the above printing method significantly reduces the number of prints using the above printing method, and the printing efficiency is significantly improved.
