Description

Printer with battery, printing control method and device thereof and storage medium

Technical Field

The present invention relates to the field of printers, and in particular, to a printer with a battery, a printing control method, a printing control device, and a storage medium.

Background

Printers are widely used as a general computer output device in work, study, and life of people. With the development of technology and the change of the work and life style, small portable printers are favored. Portable printers allow people to carry around for printing at any time.

In portable printers, it is often necessary to use a battery to power the printer, and in some printing scenarios, such as when printing an express bill, it is often necessary to print an entire horizontal line, which results in a large power consumption when printing the dot, so that exceeding the supply range of the battery causes the printer to trigger power-off protection, especially when the battery is in a low-power and low-temperature condition.

In order to ensure the normal operation of the printer, the prior art generally adopts a sectional printing mode, namely, the printing of the dot rows is realized by dividing the dot rows into a plurality of sections, but the sectional printing reduces the printing speed on one hand, and on the other hand, the printing medium and the printing head still have relative motion in the sectional printing process, so that the height difference exists in different sections, and the printing quality is reduced.

Preferably, the discarded heating points are equally spaced on the current point row.

Preferably, the method further comprises:

when judging that the heating points need to be discarded for two continuous point rows, staggering the heating points to be discarded for the two point rows in the printing direction so that the heating points discarded for the two continuous point rows are discontinuous in the printing direction.

Referring to fig. 1, a first embodiment of the present invention provides a print control method applied to a printer with a battery, comprising the steps of:

s101, calculating the current maximum heatable point number n of the heating head according to the current voltage of the battery and the heating parameters of the heating head.

In this embodiment, the output capacity of the battery is limited under low voltage or low temperature conditions, especially a 4.2V battery, and when the printer is operated, the current can reach several amperes, and the addition of the line resistance can cause the voltage supplied to the printer and the main board of the printer to be too low, which causes abnormal operation. Therefore, at low voltage or low temperature, it is necessary to ensure that the current for printing does not exceed a certain value, i.e., it is necessary to limit the maximum heatable number per printing.

In this embodiment, assuming that the current voltage of the battery is U, the current ambient temperature is T, the heating time ton=tstd of the heating head is equal to the theoretical heating time of the printing head when Tstd is the preset ambient temperature, preferably, the preset ambient temperature is 25 degrees celsius, tf is a heating compensation coefficient obtained according to the current ambient temperature T, more specifically, tf is a heating compensation coefficient obtained according to the difference between the current ambient temperature T and the preset ambient temperature Tstd, the instantaneous current i=u/R of the individual heating element on the heating head, and the rest time Toff, the average current iavg=i=ton/(ton+toff) =u×tstd×tf/R (tstd×tf+toff) of the individual heating element.

Assuming that the battery can provide an average current Isrc at the present ambient temperature T, the present maximum heatable point number n=isrc/iavg= (isrc×u×tstd×tf)/(r×tstd×tf+toff)).

S102, obtaining the heating point number Nd of the current point row.

In this embodiment, the heating point Nd of the current point line is determined according to the number of points to be printed on the current point line.

And S103, when the heating point number Nd is larger than the maximum heatable point number n, discarding at least one heating point of the current point row according to the heating point number Nd and the maximum heatable point number n to obtain an actual heating point set.

In this embodiment, when the heating point number Nd is greater than the maximum heatable point number n, it means that the heating point number Nd cannot be printed out simultaneously at one time, so this embodiment can implement one-time printing or reduce the number of segments of the segment by discarding at least one heating point of the current point line.

In this embodiment, the discarded heating points may optimize the print quality at a certain print speed or maximize the print speed at a certain print quality.

The printing speed is determined by the number of segments of the segment, and the printing speed is higher as the number of segments of the segment is smaller. The print quality is determined by the number of discarded heating points, and the smaller the number of discarded heating points is, the higher the print quality is.

However, in any case, the present embodiment needs to reduce the number of segments of the segmentation. For example, if a certain dot line originally needs to be printed in 3 segments, then if a faster printing speed is obtained, more heating dots can be discarded to reduce the segment number of the segments to 1. It is also possible to set a preset printing rate to meet the print quality requirement, so as to limit the number of discarded heating points, in which case, in order to ensure the printing instruction, the number of segments may only be 2.

Taking the latter as an example, specifically:

and when the heating point number Nd is larger than the maximum heatable point number n, acquiring the minimum printing point number Nmin of the current point line according to the heating point number Nd and a preset printing rate a.

Where the minimum print dot count nmin=nd×a.

The printing rate a here is to ensure the quality of printing without seriously affecting the printing quality by discarding too many heating points, and may be set to 75%, for example, but is not limited thereto.

if the number is larger than the number, the discarded point number is Nd-n.

That is, the discarded point is the difference between the heating point Nd and the maximum heatable point n.

And S104, printing the heating point row according to the actual heating point set.

In order to facilitate the understanding of the present invention, the following description will be given by way of practical examples.

Referring to fig. 2, fig. 2 is a content to be printed, which includes a current horizontal dot line, and assuming that the heating point nd=240 of the current dot line and the preset printing rate is 75%, the minimum printing point nmin=180.

In one embodiment, assuming that the maximum heatable point number n=200, printing in two stages is required without discarding the heating point.

In the case of discarding the heating point, since the maximum heatable point number n is greater than the minimum printing point number Nmin, the number of discarded points is 40 points.

In particular, in order to ensure the printing effect, the heating points are discarded in a manner of discarding at intervals, namely, the discarded heating points are discontinuous on the heating point row.

And in particular, the intervals of the discarded heating points are equal, the interval is 240/40=6, namely, one point is discarded every 6 points, the interval between two adjacent discarded heating points is 5, the final printing effect is as shown in fig. 3, namely, one straight line can be printed into one broken line through one-time printing, the segmented printing is avoided, and the printing speed is further improved.

In another embodiment, assuming that the maximum heatable point number n=100, 3-segment printing is required without discarding the heating point.

In the case of discarding the heating point, since the maximum heatable point n is smaller than the minimum printing point Nmin, the number of segments for obtaining the segmented printing is 2 by rounding Nmin/n upward, and the number of discarded points is 240-2×100=40.

Likewise, in order to ensure the printing effect, the heating points are discarded in a manner of discarding at intervals, that is, the discarded heating points are discontinuous on the heating point line. In particular, the heating points are equally spaced apart by 240/40=6, i.e. one point is discarded every 6 points, and the adjacent two discarded heating points are spaced apart by 5, the final printing effect is shown in fig. 3. Compared with 3-segment printing without discarding the heating point, the segment number of the segment printing of the embodiment is 2, and the printing speed is improved.

Some preferred embodiments of the invention are described further below.

On the basis of the above embodiment, in a preferred embodiment of the present invention, further comprising:

when judging that the two continuous heating point rows need to discard the heating points, staggering the heating points to be discarded of the two heating point rows in the printing direction so that the heating points discarded of the two continuous heating point rows are discontinuous in the printing direction.

In this embodiment, as shown in fig. 4, assuming that two identical long solid lines are continuously present on the print content, it is necessary to discard a certain heating point thereto. According to the general heating point discarding mode, each row of discarded heating points corresponds to each other, so that a long white line is displayed along the printing direction, and the printing effect is affected.

For this reason, in the present embodiment, the heating points to be discarded of the two heating point rows are shifted in the printing direction so that the heating points of which the two consecutive heating point rows are discarded are discontinuous in the printing direction.

For example, the first long solid line and the second long solid line are each discarded one dot every 6 dots, wherein the dots discarded by the first long solid line have a sequence number (6,12,18, the use of the first long solid line) and the dots discarded by the second long solid line have a sequence number (5, 11,17, the use of the second long solid line) or (4,10,16, the use of the second long solid line).

Taking the example of the number (4,10,16) of the discarded dots of the second long solid line, since the 4 th heating element is in a heated state when the first long solid line is printed, when the first long solid line is moved to the second long solid line, the 4 th heating element is not electrified, but still has waste heat, and the waste heat can halate the 4 th heating dot, as shown in fig. 5, so that a certain printing effect can be improved.
