Description

  The present invention relates to a program for creating barcode print data, a control apparatus for a printing apparatus that controls a printing apparatus that performs barcode printing, and a printing apparatus that performs barcode printing.

A printing apparatus such as an electrophotographic apparatus or an ink jet apparatus draws and prints characters, graphics, and the like with a set of dots called dots. As the size of the point is smaller, the number of dots constituting a character or the like is increased, and precise printing becomes possible.
The size of the point is generally expressed as a resolution.
Although depending on the type of printing apparatus, printing apparatuses having a dot density of about 100 dpi to 2400 dpi are usually commercially available depending on the application.
Many printing apparatuses connected to a personal computer or the like are 600 dpi, and some of them exceed 1200 dpi.
When printing barcodes with these printing apparatuses, printing is performed with a dot configuration that conforms to the standards of each barcode.

For example, the EAN-128 barcode (European Article Number 128: a barcode standardized by the International EAN Association), which is the barcode standard used in the convenience store fee proxy storage system, is the barcode code including the quiet zones on both sides. The total length needs to be 60 mm or less, and is composed of four types of thickness lines.
When printing such a barcode at a resolution of 600 dpi, the dot configuration of the barcode is 4 dots (a white line (hereinafter referred to as “white bar”) and a black line (hereinafter referred to as “black bar”). 0.169 mm), 8 dots, 12 dots, and 16 dots. At 1200 dp, both white and black bars are typically 9 dots (0.190 mm), 18 dots, 27 dots, and 36 dots. Since the line width is very thin and high density, printing is difficult.

Therefore, conventionally, when the amount of information recorded in a predetermined bar code width increases, the black bar and the white bar do not increase the black bar of the bar code so that the reading rate does not decrease depending on the line width condition. There is a printing apparatus (see, for example, Patent Document 1) that solves the reduction in barcode reading rate by preparing a barcode font table in which the line width is set to an appropriate width.
JP 2004-17399 A

However, in the conventional printing apparatus, depending on the printing apparatus, the black and white bar width becomes thicker as the number of printed sheets increases, and also becomes thinner, so that it is not always possible to maintain a stable thickness, leading to a decrease in reading rate. There was a problem. Similarly, the width of the black-and-white bar varies depending on the surrounding environment such as temperature and humidity, which causes a reading problem.
In addition, depending on the bar code bar direction, the black and white bar thickness varies depending on the model due to variations in the beam diameter of the laser beam, speed variations in paper conveyance, etc., depending on the model. Will occur.

〔Example〕
FIG. 2 is a block diagram showing the configuration of an electrophotographic printer (hereinafter referred to as “printer”) which is an embodiment of the printing apparatus of the present invention.
FIG. 2A shows a schematic configuration diagram of the entire printer, and FIG. 2B shows a configuration of a process cartridge configured to be detachable from the printer main body.
In FIG. 2, a printer 20 is an image forming apparatus, and the peripheral surface of the photosensitive member 1 as a latent image carrier is uniformly driven to a positive or negative predetermined potential by the charging device 2 while being rotated at a predetermined peripheral speed. After being charged, the image exposure apparatus 3 such as slit exposure or laser beam scanning exposure performs scanning exposure processing based on the image information to form an electrostatic latent image.

The electrostatic latent image formed on the photoreceptor 1 is developed by the developing device 4 to become a toner image.
The toner image formed on the photosensitive member 1 passes through the registration roller 6 and the conveyance guide plate 7 from the paper feeding cassette 5 and is synchronized with the rotation of the photosensitive member 1 between the photosensitive member 1 and the transfer roller 8. The image is transferred by the transfer roller 8 onto the fed transfer material.
The transfer material onto which the toner image has been transferred in this manner is separated from the peripheral surface of the photoreceptor 1 and sent to the image fixing device 9, where the toner image is fixed and then copied as a copy (copy). It is discharged out of the printer 20.

The surface on the photoreceptor 1 after the image transfer is cleaned by removing the transfer residual toner by the cleaning device 10, and is neutralized by a known neutralization device (not shown) and used for the next image formation. .
The constituent elements of the photoreceptor 1, the charging device 2, the developing device 4, and the cleaning device 10 described above are detachably supported on the main body of the printer 20 as an integrally formed process cartridge 11.
Although not shown in the figure, a control unit realized by a microcomputer including a CPU, a ROM, and a RAM is also provided, and the control unit controls overall processing of the printer 20.

FIG. 1 is a block diagram showing a configuration of a printing system according to an embodiment of the present invention.
The printing system includes a printer 20 which is an embodiment of the printing apparatus of the present invention, and a computer 30 which is an embodiment of the control apparatus of the printing apparatus of the present invention.
The computer 30 includes a memory 31 realized by a microcomputer including a CPU, ROM, and RAM, a barcode data creation unit 32, a direction detection unit 34, and a dot correction unit 35. The printer driver 33 causes the printer 20 to print. Information.
That is, when the barcode printing according to the present invention is realized by the control of the computer 30, the program according to the present invention is stored in the RAM of the computer 30, and the barcode data creating unit 32 executes this program when the CPU executes the program. The direction detection unit 34 functions as a detection unit and a determination unit according to the printing apparatus control device of the present invention, and the dot correction unit 35 performs printing according to the present invention. It fulfills the functions of correction means and output means related to the control device of the apparatus.

  On the other hand, the printer 20 includes each unit shown in FIG. 2 and has a control unit 21 that controls the entire printer 20 (not shown in FIG. 2), and realizes barcode printing according to the present invention with the printer 20. In this case, the control unit 21 performs the functions of the creation unit, the detection unit, the determination unit, and the correction unit according to the printing apparatus of the present invention. The control unit 21 and each unit illustrated in FIG. Fulfill.

When normal bar code printing is performed by this printing system, as shown in FIG. 3, the module width of one black bar may become narrower (narrower) as the number of printed sheets of recording paper increases.
As shown in FIG. 4, the one module width is the thinnest bar 40 among the four types of bars 40 to 43 constituting the barcode, and the line width of the bar 40 is narrowed.
The other bars are a bar 41 having a line width twice that of the bar 40 having a module width, a bar 42 having a line width three times, and a bar 43 having a line width four times that of the module 40. The bar code is composed of four types of bar widths, and the four types of line widths are the same for both the white bar shown in FIG. 5A and the black bar shown in FIG. is there.

The reason why the line width of the black bar becomes thinner in accordance with the number of printed sheets described above is due to the increase in the charge amount of the developer due to the two-component development, and when printing the barcode described above, the thickness is always stable. Cannot be maintained, leading to a problem that the barcode reading rate is lowered.
In order to solve the problem, this printing system creates barcode print data based on image data including barcode information, and then, as shown in FIG. And a dot correction process that corrects the number of dots of one module width as the number of printed sheets increases the number of dots of the line width of the white bar (also referred to as “white space”), and the barcode is printed on the recording paper with the corrected print data To print.

FIG. 6 is a diagram showing the number of dots when printing one module width of a black bar and a white bar of a barcode at each resolution of 400 dpi, 600 dpi, and 1200 dpi.
As shown in the figure, it can be seen that the number of dots forming one module width differs depending on the resolution.
For example, when printing is performed at a resolution of 1200 dpi, the above dot correction processing is performed so as to vary the number of dots by increasing the number of black bars in the print data and decreasing the number of white bars.

The initial number of dots of one module width at a resolution of 1200 dpi is 9 dots for both black and white bars, and the correction value of 0 when the number of printed sheets (number of sheets passed) shown in FIG. 5 is 0 for both the white and black bars. It means the initial value of 9 dots. One dot at a resolution of 1200 dpi is about 0.021 mm.
Further, the dot correction process changes only the ratio of the white bar and the black bar without changing the value obtained by adding the number of dots of the black bar and the white bar.
FIG. 7 is a diagram showing the transition of the width of one module after the dot correction processing according to the number of printed sheets. Even when the line width of the black bar becomes thin according to the number of printed sheets, Based on the barcode printing, as shown in the figure, even if the number of printed sheets increases, fluctuations in the line width of the barcode can be suppressed within a predetermined range, and the line width of the barcode can be stabilized. Can be maintained.

Next, as shown in FIG. 8, the line width of the black bar of the barcode may become thicker (wider) depending on the number of printed recording sheets.
This is mainly due to one-component development, and the charge amount of the toner increases as the number of printed sheets increases from the initial stage, and the developability is improved from the initial stage. In this way, even if the thickness is naturally increased, the thickness cannot be maintained, so that the barcode reading rate is lowered.
Therefore, in this printing system, after the barcode print data is created based on the image data including the barcode information, as shown in FIG. As the number of prints increases, dot correction processing for correcting the number of dots of one module width is performed, and a barcode is printed on the recording paper with the corrected print data.

In the dot correction processing in this case, as shown in FIG. 9, the number of black bar dots is decreased and the number of white bar dots is increased so that the line width of the black bar of the barcode is reduced according to the number of printed sheets. Correction to change the number of dots.
In this way, even when the line width of the black bar becomes thicker according to the number of printed sheets, even if the number of printed sheets increases as shown in FIG. 10 by bar code printing based on the print data subjected to the dot correction processing. The thickness of the line width can be maintained stably.

Next, the barcode printing process based on the print data subjected to the dot correction process on the computer 30 side will be described with reference to FIG.
First, in step (indicated by “S” in the figure) 1, a numerical value of the number of printed sheets counter is requested from the computer control unit to the printer.
The printed sheet counter is counted up by one count for each sheet of recording paper to be printed and is built in the main body of the printer 20.
In step 2, when the control unit of the printer main body engine receives a request for the number of printed sheet counters from the computer, it returns the number of printed sheet counters to the computer in step 3.

In step 4, when the control unit of the computer receives the value of the number of printed sheets counter from the printer, in step 5, the bar code data generating unit performs bar code matching the resolution of the printer engine based on the image data including bar code information. In step 6, the above-described dot correction processing corresponding to the number of prints based on the value of the print number counter from the printer is applied to the print data. In step 7, the print data after the dot correction processing is stored in the main body of the printer. Send to engine control (output from computer to printer).
When the control unit of the printer main body engine receives print data from the computer in step 8, a barcode is printed on the recording paper based on the print data in step 9, and this process is terminated.

  In addition, in the case of performing barcode printing based on the print data subjected to dot correction processing on the printer 20 side, the control unit 21 of the printer 20 includes an image including barcode information given from the computer 30 which is an external device. After the data is expanded on the internal memory, barcode print data is created, and the created print data is subjected to dot correction processing similar to that described above. Based on the corrected print data, a bar code is printed on the recording paper by the engine unit. Print the code.

Next, as shown in FIG. 12, the line width of the black bar of the barcode may vary depending on the ambient temperature during barcode printing.
The effect is that the charge amount of the developer fluctuates depending on the ambient temperature environment. When the temperature is low, the charge amount increases, so the developing ability is lowered and the line width of the black bar becomes narrow (narrow). On the other hand, when the temperature is high, the charge amount decreases and the developability increases, so that the toner amount is increased and the black bar has a wide (wide) line width.

Therefore, in this printing system, after the barcode print data is created based on the image data including the barcode information, as shown in FIG. 13, the print data is printed according to the ambient temperature of the printer 20. It is preferable to perform dot correction processing to vary the number of dots of the black bar line width and the number of white bar line widths, and print the barcode on the recording paper with the corrected print data.
For example, the dot correction process may be performed when the temperature around the printer 20 is 31 ° C. or higher.
In this way, even when the line width of the black bar of the barcode fluctuates according to the ambient temperature during barcode printing, the barcode printing based on the print data subjected to the dot correction processing shown in FIG. As described above, the thickness of the line width can be stably maintained.

Next, as shown in FIG. 15, the line width of the black bar of the barcode may vary depending on the ambient humidity during barcode printing.
Therefore, in this printing system, after the barcode print data is created based on the image data including the barcode information, as shown in FIG. 16, the print data is printed according to the ambient humidity of the printer 20, as shown in FIG. It is preferable to perform dot correction processing to vary the number of dots of the black bar line width and the number of white bar line widths, and print the barcode on the recording paper with the corrected print data.
In this way, even when the line width of the black bar of the barcode fluctuates in accordance with the ambient humidity at the time of barcode printing, the barcode printing based on the print data subjected to the above dot correction processing is shown in FIG. As described above, the thickness of the line width can be stably maintained.

Next, the barcode printing process based on the print data subjected to the dot correction process on the computer 30 side will be described with reference to FIG.
First, in step (indicated by “S” in the figure) 11, the computer controller requests the printer for ambient temperature and humidity values.
Assume that the main body side of the printer 20 includes a temperature sensor and a humidity sensor for measuring the temperature and humidity around the printing engine unit.
In step 12, when the control unit of the printer main body engine receives a request for numerical values of temperature and humidity from the computer, the numerical value of temperature and humidity measured by the built-in temperature sensor and humidity sensor in step 13 are returned to the computer.

When the controller of the computer receives the numerical values of the temperature and humidity from the printer in step 14, the barcode data generation unit in step 15 performs the barcode that matches the resolution of the printer engine based on the image data including the barcode information. In step 16, the above-described dot correction processing corresponding to the temperature and humidity values from the printer is applied to the print data. In step 17, the print data after the dot correction processing is controlled by the printer engine. To the printer (output from the computer to the printer).
When the control unit of the printer main body engine receives the print data from the computer in step 18, a bar code is printed on the recording paper based on the print data in step 19, and this process ends.

The temperature and humidity may be controlled separately. However, if the temperature and humidity are simultaneously detected and dot correction processing is performed as described above, fluctuations in the line width of the black bar during printing can be achieved. It is more effective to suppress.
In this embodiment, the temperature sensor and humidity sensor built in the printer are used to measure the ambient temperature and humidity of the engine unit related to printing of the printer. However, the temperature and humidity are measured by other measurement methods. You may make it measure.
For example, a method of detecting a resistance value of a rubber roller such as a transfer roller and detecting temperature and humidity based on the resistance value is also effective.

  In addition, in the case of performing barcode printing based on the print data subjected to dot correction processing on the printer 20 side, the control unit 21 of the printer 20 includes an image including barcode information given from the computer 30 which is an external device. After the data is expanded on the internal memory, barcode print data is created, and the created print data is subjected to dot correction processing similar to that described above. Based on the corrected print data, a bar code is printed on the recording paper by the engine unit. Print the code.

Next, the line width of the black bar and the white bar may differ depending on the bar direction of the barcode during printing.
FIG. 19 is a diagram showing that the bar direction of the bar code is parallel to the developing direction at the time of printing, and the bar code bar direction is parallel to the developing direction at the time of printing. The line widths of the black bar and white bar printed with may be different.
This is because the difference between the laser beam diameter on the surface of the photoreceptor image of the laser that is the exposure means of the printer, and the trailing edge of the developing direction of the toner image formed on the photoreceptor by the developer brush on the developing sleeve. It is known that this is the cause of scratching.
For these reasons, the line width of the black bar of the barcode perpendicular to the developing direction at the time of printing becomes narrower (narrower) than the line width of the parallel black bar.

  In order to solve the problem, in this printing system, after creating the barcode print data based on the image data including the barcode information, the direction of the barcode bar of the print data is detected and detected. It is determined whether or not the bar code bar direction matches the development direction during printing, and correction is performed to vary the number of black bar dots and white bar dots in the created print data according to the determination result. It is good to do.

First, image data including barcode information and paper setting information of a recording sheet on which the barcode is printed are input to the computer 30, and barcode print data is generated based on the image data including the barcode information by the barcode data creation unit 32. The direction detector 34 detects the bar direction of the bar code of the print data. In order to detect the direction of the bar, it is only necessary to check whether or not the black portion of the image data continues for a predetermined length (the minimum length of the bar) or not.
Then, whether the detected bar code bar direction is perpendicular to the printing direction of the recording paper (that is, with respect to the developing direction during printing), as shown in FIG. As shown in (b) of FIG. That is, based on this determination, it is determined whether or not the detected bar code direction matches the developing direction at the time of printing.

Based on the result of the above determination, print data dot correction processing is performed. When it is determined that the bar direction of the bar code is perpendicular to the developing direction, and when the bar code is determined to be parallel, the white bar of the bar code and The correction processing for changing the number of dots of the black bar is made different.
For example, as shown in FIG. 19B, when the bar code direction is parallel to the printing direction of the recording paper, the dot correction unit does not perform correction for changing the number of dots, and FIG. As shown in (a), when the bar code bar direction is perpendicular to the printing direction of the recording paper, the line width of the black bar is reduced because the line width of the actual black bar is reduced by the dot correction unit. Correction is performed by increasing the width by 1 dot and reducing the line width of the white bar by 1 dot, and the corrected print data is output to the printer.

  In addition, in the case of performing barcode printing based on the print data subjected to dot correction processing on the printer 20 side, the control unit 21 of the printer 20 includes an image including barcode information given from the computer 30 which is an external device. After the data is expanded on the internal memory, barcode print data is created, the barcode bar direction of the print data is detected, and the detected barcode bar direction matches the development direction during printing. In accordance with the determination result, correction is made to vary the number of black bar dots and white bar dots in the created print data, and recording is performed by the engine unit based on the corrected print data. Print barcodes on paper.

  In this way, correction of the number of dots of the black bar and the white bar according to the number of printed sheets, the temperature and humidity environment, and the direction in which the bar of the bar code extends may be performed independently, but a plurality of them are combined. If the control is performed, the line width of the black bar of the barcode can be corrected with high accuracy, and the thickness of the line width of the black bar after printing the barcode can be stably maintained.

  The printing apparatus according to the present invention can also be applied to a copying machine and a facsimile machine. The control device for a printing apparatus according to the present invention can also be applied to a desktop personal computer and a notebook personal computer.
