Description

Technical Field

[0001] The present disclosure relates to the field of printing technology, and in particular to a printer control method, device, electronic device, and storage medium. Background Art

[0002] With the development of information technology, information management system software has been widely used in all walks of life and is widely used to print various documents and reports. However, there are often some problems when printing documents and reports. Since the printing paper used for printing documents and reports is usually chain paper, the current printer cannot stay at the nearest paper cutting line after completing printing on the chain paper. Instead, no matter how much content is printed, the paper is fed in units of one page of chain paper during printing (one page of chain paper refers to one page of chain paper with a full number of holes within multiple paper cutting lines). This easily causes paper waste and is inconvenient for users to tear paper. Summary of the Invention

[0056] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0057] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0058] Figure 1 is a flow chart showing a printer control method according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the printer control method may include the following steps.

[0059] In step S101, the number of holes in one page of chain paper and the number of cut sheets in one page of chain paper are determined based on information of the loaded chain paper.

[0060] The printer may be a dot matrix printer, and the chain paper is chain printing paper, also known as folding printing paper, carbon printing paper, and equal-division printing paper. The chain paper information may include the paper type of the chain paper. The printer may pre-store paper parameters corresponding to different paper types. The paper parameters may include, for example: the paper height of a page of chain paper (the paper height here refers to the maximum height of a page of chain paper. For example, the chain paper used for printing documents is generally B5, that is, a chain paper with a total length of 22n inches. A page of chain paper refers to a page of chain paper with a whole number of holes within multiple cutting lines. For a chain paper with a total length of 22n inches, the paper height of a page of chain paper is 22 inches, and n represents the total number of pages of the entire chain paper), the number of paper cuts (or the number of paper cuts), the number of paper holes (the number of holes in each embodiment of the present application refers to the number of whole cut holes), etc.

[0061] For example, chain paper is often used for documents or reports. The paper parameters of the chain paper used for printing documents and reports are different. For example, the chain paper used for printing documents is usually B5 length, with a total length of 22n inches. The number of holes for cutting a page of this chain paper is usually 27, and the number of cut sheets is 3. The chain paper used for printing reports is usually B3 length, with a total length of 22n inches. The number of holes for cutting a page of this chain paper is usually 27, and the number of cut sheets is 1 (which can be understood as the chain paper is not cut). Therefore, in this solution, it is necessary to first obtain information about the chain paper loaded in the printer to identify the paper type of the chain paper, thereby determining the number of holes and the number of cut sheets in a page of the chain paper. The chain paper information can be manually set by the user on the printer after loading the chain paper, or it can be sent to the printer via the printer's control device (such as the user's computer or mobile terminal).

[0062] In step S102, the cutting line height of the inner page is determined according to the number of holes and the number of paper cuts. The inner page is any page of the chain paper divided according to the cutting line. The cutting line height is the distance between two cutting lines of the inner page.

[0063] It is understood that there are multiple paper holes on the chain paper, which are evenly arranged on both sides of the chain paper according to a certain hole spacing. For example, Figure 2 is a schematic structural diagram of a chain paper according to an exemplary embodiment. Figure 2As shown, this chain paper is used for printing documents. A page of chain paper has 27 paper holes, which are divided into three inner pages by a paper cut line. Each inner page has nine paper holes. The hole spacing between the nine paper holes in each inner page is generally 0.5 inches. This hole spacing is the distance from the top edge of the first paper hole to the top edge of the second paper hole in any two adjacent paper holes. In each inner page, the top edge of the first paper hole coincides with the paper cut line at the top of the inner page, and the bottom edge of the last paper hole coincides with the paper cut line at the bottom of the inner page (coincidence can also be understood as tangent).

[0064] The number of holes on a page of chain paper (the number of holes on both sides is the same, and the number of holes on either side can be the same) is divided by the number of sheets of paper to be cut (for example, there are 3 sheets of paper for a document and 1 sheet of paper for a report, determined according to actual conditions) to get the number of holes on each inner page. Then, the number of holes on each inner page is multiplied by the hole spacing of the chain paper to get the height of the paper cut line for each inner page. Therefore, the height of the paper cut line can be calculated as follows:

[0065] The quotient obtained by dividing the number of holes by the number of paper cuts is multiplied by the hole spacing of the chain paper to obtain the paper cutting line height. It can be expressed as:

[0066] hegihtpage=numhole / numpage*d

[0067] Among them, hegihtpage represents the height of the inner page, that is, the height of the paper cutting line, numhole represents the number of holes in a page of chain paper, numpage represents the number of paper cutting sheets, and d represents the hole spacing. Figure 2 Taking the chain paper shown as an example, the cutting line height of the inner page = 27 ÷ 3 × 0.5 inches = 4.5 inches.

[0068] For another example, if it is chain paper (not shown) used for printing reports, the number of paper cuts is 1 and the number of holes is 27, then the paper cut line height = 27 ÷ 1 × 0.5 inches = 13.5 inches.

[0069] In addition, it is worth mentioning that the number of paper holes and the number of paper cutting pages are only exemplary and may be other numbers, which can be determined according to the actual situation of the chain paper.

[0070] In step S103 , the printing line spacing and the number of printing lines of the inner pages are determined according to the paper cutting line height.

[0071] It can be understood that the printing line spacing and number of printing lines of the inner page can be determined according to the height of the paper cutting line. When the height of the paper cutting line is equal to an integer multiple of the printing line spacing, it can be ensured that the content to be printed can be printed completely on the inner page without exceeding or missing any printing content.

[0072] In step S104 , the printing height of the inner page is determined according to the printing line spacing and the number of printing lines.

[0073] It is understandable that the number of printed lines is the total number of printed lines in each inner page. Therefore, in one embodiment, the print height of the inner page can be calculated as follows:

[0074] The value obtained by multiplying the number of print lines of the inner page by the print line spacing is the print height of the inner page.

[0075] In step S105 , the chain paper is printed according to the printing line spacing and printing height.

[0076] It can be understood that by controlling the line spacing and print height of the inner pages, the chain paper can be fed using the inner pages as the paper feed unit when printing. Therefore, regardless of the amount of printed content, the paper will stop at the nearest paper cut line after printing, making it easier to tear the paper. Moreover, compared to the prior art, when printing, the paper is fed as a single page of chain paper regardless of whether the printed content can fill a page, which can reduce paper waste to a certain extent.

[0077] Optionally, Figure 3 is a flow chart showing another printer control method according to an exemplary embodiment of the present disclosure, such as Figure 3 As shown, step S103 may include the following steps:

[0078] In step S1031, when the height of the paper cutting line is less than the maximum height of a page of chain paper, a first value is obtained from a preset line spacing array, where the line spacing array includes multiple values used to represent the size of the line spacing.

[0079] Among them, taking the maximum height of a page of chain paper as an example, in this embodiment, the maximum height of a page of chain paper can be 22 inches. If the height of the paper cutting line is less than the maximum height of a page of chain paper, the subsequent steps can be continued. If the height of the paper cutting line is greater than the maximum height of a page of chain paper, the current printing task can be stopped and a warning message of paper abnormality can be output.

[0080] Since the printing line spacing of a dot matrix printer is usually 1 / 6 inch, 1 / 8 inch, n / 60 (n ranges from 1 to 85) inch, n / 180 (n ranges from 1 to 255) inch, and n / 360 (n ranges from 1 to 255) inch, multiple values can be set to represent the size of the line spacing, namely 6, 8, 60, 180, 360, and {6, 8, 60, 180, 360} is used as the above-mentioned line spacing array, and values are selected from the line spacing array in sequence as the first value to perform steps S1032-S1034 to determine the final value of the first value and the value of the above-mentioned n, thereby determining the final printing line spacing and number of printing lines.

[0081] In step S1032 , the number of rows corresponding to the first value is determined according to the paper cutting line height and the first value.

[0082] In step S1033 , when the number of lines corresponding to the first value is an integer, the number of lines corresponding to the first value is determined as the number of printing lines, and the line spacing corresponding to the first value is determined as the printing line spacing.

[0083] In step S1034, when the number of rows corresponding to the first value is not an integer, the next value in the row spacing array is used as the new first value, and the step of determining the number of rows corresponding to the first value based on the paper cutting line height and the first value is performed again until the number of rows corresponding to the first value is an integer.

[0084] For example, since, in the above-mentioned printing line spacing, when the printing line spacing is 1 / 6 inch and 1 / 8 inch (i.e., when the first value is 6 and 8), it is not necessary to determine the value of n, but when the printing line spacing is n / 60 inch, n / 180 inch, and n / 360 inch (i.e., when the first value is 60, 180, and 360), it is necessary to determine the value of n, different calculation methods can be used for the above-mentioned two cases. For example, taking 8 as the specified value below as an example, the following steps can be included:

[0085] When the first value is less than or equal to the specified value, step S1032 may be: multiplying the paper cutting line height by the first value as the number of rows corresponding to the first value.

[0086] It can be understood that the number of rows of the inner page = the height of the paper cutting line ÷ the line spacing, where the line spacing corresponding to the first value is the value obtained by multiplying the reciprocal of the first value by the specified line spacing unit. Therefore, the value obtained by dividing the paper line height by the reciprocal of the first value and multiplying the specified line spacing unit is equivalent to multiplying the paper cutting line height by the first value. Therefore, the product of the paper cutting line height and the first value is taken as the number of rows corresponding to the first value. The number of rows corresponding to the first value can be understood as the number of rows of the inner page under the line spacing corresponding to the first value.

[0087] That is, when the first value is 6 or 8, the number of rows corresponding to the first value is calculated using the following formula:

[0088] linepage=hegihtpage*minbase[i] (1)

[0089] Among them, linepage represents the number of lines corresponding to the first value, hegihtpage represents the height of the paper cutting line, minbase[i] represents the first value, and i represents that the current first value is taken from the i-th value in the above line spacing array {6, 8, 60, 180, 360}.

[0090] Accordingly, step S1033 may include:

[0091] When the number of lines corresponding to the first value is an integer and is less than or equal to the maximum number of lines for a page of chain paper, the number of lines corresponding to the first value is determined as the number of lines to be printed. The maximum number of lines for a page of chain paper is the maximum number of lines under the line spacing corresponding to the first value. The line spacing corresponding to the first value is a value obtained by multiplying the reciprocal of the first value by a specified line spacing unit. The specified line spacing unit can be inches. For example, when the first value is 6, i.e., the corresponding line spacing is 1 / 6 inch, the maximum number of lines is 127.

[0092] The line distance corresponding to the first value is used as the printing line distance.

[0093] If the number of rows corresponding to the first value is not an integer, or the number of rows corresponding to the first value is greater than the maximum number of rows for the chain paper, then exit, select the next value from the above-mentioned row spacing array {6, 8, 60, 180, 360} as the new first value, and execute the above steps again.

[0094] Among them, when the first value is 6 or 8, that is, the line spacing is 1 / 6 inch or 1 / 8 inch, the maximum number of lines can be 127. For example, when minbase[i]=6, if the number of lines linepage corresponding to minbase[i]=6 is an integer and less than or equal to 127, then linepage is used as the final number of printed lines, and 1 / 6 inch is used as the printing line spacing; if the number of lines linepage corresponding to minbase[i]=6 is not an integer or greater than 127, then 8 is taken from {6, 8, 60, 180, 360} and the above formula (1) is used again to calculate linepage. If the number of lines linepage corresponding to minbase[i]=8 is an integer and less than or equal to 127, then linepage corresponding to minbase[i]=8 is used as the final number of printed lines, and 1 / 8 inch is used as the printing line spacing. Otherwise, the calculation is performed according to the following situation where the first value is greater than the specified value.

[0095] When the first value is greater than the specified value, step S1032 may include:

[0096] (1) extracting a second value from a preset value range corresponding to the first value;

[0097] Among them, taking the above-mentioned line spacing array {6, 8, 60, 180, 360} as an example, the case where the first value is greater than the specified value is that the line spacing array is 60, 180 or 360. In this case, the corresponding line spacings are k / 60 (k ranges from 1 to 85) inches, n / 180 (n ranges from 1 to 255) inches, and k / 360 (n ranges from 1 to 255) inches. Therefore, according to the value of the first value, the corresponding preset value range can be determined. For example, when the first value is 60, the corresponding preset value range is 1 to 85, when the first value is 180, the corresponding preset value range is 1 to 255, and when the first value is 360, the corresponding preset value range is 1 to 255. After obtaining the preset value range corresponding to the first value, traverse from the first number in the preset value range and perform the steps shown in the following steps (2)-(3) in sequence.

[0098] (2) The quotient obtained by dividing the product of the paper cutting line height and the first value by the second value is used as the number of rows to be selected.

[0099] It can be understood that since the first value is taken from the line spacing array {60, 180, 360}, the corresponding line spacings are k / 60 inches, k / 180, and k / 360, respectively. Therefore, the line spacing is represented by k / minbase[i]. The corresponding number of rows can be obtained by dividing the height of the paper cutting line of the inner page by k / minbase[i]. Therefore, the following formula (2) can be obtained.

[0100] That is, when the first value is 60, 180 or 360, the number of rows corresponding to the first value is calculated by the following formula:

[0101] linepage=hegihtpage*minbase[i] / k (2)

[0102] Among them, linepage represents the number of lines corresponding to the first value, hegihtpage represents the height of the paper cutting line, minbase[i] represents the first value, i represents the current first value is taken from the i-th value in the above line spacing array {6, 8, 60, 180, 360}, and k represents the second value currently taken from the preset value range.

[0103] (3) When the number of rows to be selected is not an integer, the next value is extracted from the preset numerical range as the new second value, and step (2) is executed again until the number of rows to be selected is an integer or the second value is the last value in the preset numerical range, and the number of rows to be selected is used as the number of rows corresponding to the first value.

[0104] Accordingly, step S1033 may include:

[0105] When the number of lines to be selected is an integer, a value obtained by multiplying the current ratio of the second value to the first value by a specified line spacing unit is used as the printing line spacing.

[0106] For example, when minbase[i]=60, starting from k=1, traverse one by one in the range of 1 to 85 to calculate the corresponding linepage, until there is a value x in 1 to 85 such that the linepage calculated using the above formula (2) is an integer. At this time, when minbase[i]=60 and k=x, the linepage calculated can be determined as the first value, that is, the number of lines corresponding to minbase[i]=60, which can be used as the final number of printing lines, and x / 60 inches is the printing line spacing; if the linepage calculated by traversing one by one in the range of 1 to 85 until k=85 is traversed is also not an integer, it means that the first value, that is, the number of lines corresponding to minbase[i]=60, is not an integer, and it is necessary to take another value 180 from {6, 8, 60, 180, 360} and repeat the above steps (2)-(3) based on the value range 1 to 255 corresponding to minbase[i]=60, and so on, until the calculated linepage is an integer.

[0107] By using the above method, it can be ensured that the height of the paper cutting line is equal to an integer multiple of the printing line spacing.

[0108] Optionally, Figure 3 is a flowchart of another printer control method according to an exemplary embodiment of the present disclosure, such as Figure 3 As shown, step S105 may include the following steps:

[0109] In step S1051 , the target number of lines to be printed is determined according to the printing content.

[0110] In step S1052, the total printing height is determined according to the target number of lines and the printing line spacing.

[0111] For example, the product obtained by multiplying the target number of lines by the printing line spacing is the total printing height.

[0112] In step S1053, the quotient of the total printed height divided by the printed height of the inner pages is rounded up to an integer, which is used as the number of inner pages fed.

[0113] It is understandable that rounding up is to ensure that the printed content can be completely printed without missing any content.

[0114] In step S1054, the chain paper is printed according to the printing line spacing, the printing height of the inner pages, and the number of inner pages of the paper feed.

[0115] It is understandable that the number of inner pages fed can be determined based on the printing height of the inner pages. For example, when printing, the number of inner pages can be increased by 1 for each inner page printed, thereby monitoring the current number of paper feeds. When the above number of inner pages fed is reached, the current inner page is the last inner page to be printed. When the last inner page is printed, printing is stopped to ensure that it stops at the nearest paper cutting line. Through the above method, the inner page can be used as the paper feeding unit. If the printed content is small and not enough to use a page of chain paper, the paper will be fed to the nearest paper cutting line after printing is completed. Compared with the existing printing method, even if only one line of content is printed, a page of chain paper will still be fed, which reduces paper waste to a certain extent.

[0116] Through the above technical solution, the appropriate printing line spacing and number of lines can be determined according to the number of holes and the paper cutting line of the chain paper, and the printing height of each inner page can be determined accordingly, so that the printer uses the inner page as the paper feeding unit when printing, so that after printing is completed, it can stay at the nearest paper cutting line position, which is convenient for the operator to tear the paper manually and avoids paper waste caused by excessive paper feeding of the printer.
