Detailed description of the invention
Based on the defect of prior art, a kind of bar code printer disclosed in this invention prints the method for horizontal bar code.
As shown in Figure 1, the method that bar code printer prints horizontal bar code comprises the following steps:
Step S10: according to printhead precision confirmed standard resolution chart, print described standardized test chart.
As shown in Figure 2, standardized test chart is made up of two large divisions, comprises standard bar code district 21 and compensating test district 22.In this example, suppose that this resolution chart is that the printer of above-below direction paper delivery in Fig. 2 printed, be understood that, the stroke of the printhead of this printer is left and right directions in Fig. 2 accordingly.
Wherein, standard bar code district 21 comprises the longitudinal bar code 201 of the standard printed by upper and lower page orientation, and (bar in bar code and empty orientation are longitudinal arrangement, namely bar and empty bearing of trend parallel with in page orientation same plane), for as the test benchmark after resolution chart printing.
Compensating test district 22 comprises offset and (is numbered in Fig. 2 by five groups of horizontal bar codes of 1 to 5 arrangements and be respectively 202 ~ 206, bar in bar code and empty orientation are transversely arranged, namely bar is vertical in same plane with page orientation with empty bearing of trend), for testing actual printing effect, described offset represents the quantity of the heating print unit compensated in a millimeter.In the district of compensating test shown in Fig. 2 22, the offset of five groups of bar codes confirms to comprise the following steps:
S101: determine compensation rate scope according to printhead precision d;
Described printhead precision d represents the quantity of the heating print unit in a millimeter, and the standard of common printhead precision d comprises 6,8 or 12.In this step compensation rate scope, minimum compensating value is 1, and the available accuracy d of maximum offset n and printhead matches, i.e. n=d.In the present embodiment, printhead precision d=5, then maximum offset n=d=5, namely compensate 5 heating print units in one millimeter.
S102: according to the bar code in different offset determination compensating test district 22.
According to the compensation rate scope determined in step S101, determine the offset of each group bar code in compensating test district 22, for Fig. 2, the offset of five groups of bar codes then in compensating test district 22 is respectively 1,2,3,4,5, namely in one millimeter, compensating 1 ~ 5 heating print unit respectively.
S103: the bar code printing standard bar code district 21 and compensating test district 22.
Step S20: by contrasting with standardized test chart, determine optimal compensation value from compensation rate scope.
Contrast can adopt manual type to carry out, 90 ° are rotated clockwise by standard bar code district 21, respectively with five groups of bar code comparisons one by one in compensating test district 22, to confirm the wide immediate one group of bar code of bar code-bar in compensating test district 22, confirm that the offset of this bar code is for optimum, namely determines optimal compensation value t.
Preferably, also can adopt and confirm optimal compensation value in an automated fashion, namely by image recognition technology, first identify that each bar code-bar of also record standard bar code district 21 Plays bar code 201 is wide; Secondly, to identify and to record each bar code-bar of five groups of bar codes in compensating test district 22 wide; Then, carry out bar width ratio comparatively by corresponding respectively for each group of bar code in compensating test district 22 with standard bar code 201, to confirm the wide immediate one group of bar code of bar code-bar, and then the offset of this group bar code is set to optimal compensation value t.
Step S30: judge that the bar code printed is the need of correction.
In this step, judge that the bar code printed comprises the need of the step revised:
Step S301: judge bar code printing direction.
When according to page orientation upper and lower shown in Fig. 2, and bar code printing as standard bar code district 21 Plays bar code 201 time, the bar namely in bar code and empty orientation are longitudinal arrangement, and bar and empty bearing of trend are with when paralleling in page orientation same plane, now without the need to compensating, enter step S50; Otherwise five groups of bar codes in bar code printing is as compensating test district 22, the bar namely in bar code and empty orientation are transversely arranged, when bar is vertical in same plane with page orientation with empty bearing of trend, enter step S202.Bar code printing direction is judged by print routine.
Step S302: judge whether the barcode size r printed can meet compensation requirement.
Described barcode size r represents the heating print unit quantity comprised in bar code minimum widith unit.Described minimum widith unit refers to the width of the width minimum unit of the bar code that actual needs prints.In this step, determine whether to meet by the difference calculated in barcode size r and step S20 between the optimal compensation value t that determines and compensate requirement, i.e. r-t >=1.When not meeting above-mentioned expression formula, namely without the need to carrying out correction-compensation, entering step S50, otherwise entering step S40.The condition arranging r-t >=1 its object is to: after making correction-compensation, at least can retain a print unit print in the position of bar.Otherwise the width of bar may be corrected for 0, in such cases, this would not be printed.
Step S40: correction-compensation is carried out to bar code according to optimal compensation value.
As shown in Figure 3, in figure, the actual bar width exported is 302, and compensate according to the optimal compensation value t determined in step S20, the optimal compensation value t namely in figure shown in 303, namely reaches bar code normal width 301 after compensation.
Step S50: directly print bar code, does not do correction-compensation process.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all in a word, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
