Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a medium on which a paper discharge program is recorded, a medium on which a data identification program is recorded, a paper discharge apparatus, a data identification apparatus, a paper discharge method, and a data identification method.
[0002]
[Prior art]
  In order to print a document, a drawing, or the like from a computer using a printer, a driver, a spooler, a language monitor, and the like are usually transferred on the computer to the printer. That is, the spooler temporarily spools the print data generated by the driver, and the language monitor monitors the status of the printer and supplies an appropriate amount of data to the printer at an appropriate timing.
[0003]
[Problems to be solved by the invention]
  The conventional printing described above has the following problems. In other words, when a user cancels printing, if the driver cancels printing, the driver can output a command for canceling processing in the printer, but the user prints after data is transferred to the spooler. When canceling is canceled, the printer may not be able to perform an appropriate cancellation process, and the printing paper may not be discharged. In such a case, it may be possible to discharge the printing paper with the discharge button provided in the printer itself. However, such a discharge cannot be performed with a low-cost printer that does not have the discharge button. It is necessary to open the printer cover and remove the printing paper.
[0004]
  The present invention has been made in view of the above problems, and a medium on which is recorded a paper discharge program capable of causing the printer to discharge print paper without bothering the user even when printing cancellation by the spooler is made, It is an object of the present invention to provide a medium on which a data identification program is recorded, a paper ejection device, a data identification device, a paper ejection method, and a data identification method.
[0005]
[Means for Solving the Problems]
  In order to achieve the above object, the invention according to claim 1 is a medium on which is recorded a paper discharge program for discharging print paper by a printing apparatus when a print job is canceled by the spooler, and the spooler outputs the medium. The tail in spool dataFrom the predetermined sizeDataStoreThis function is activated when the spool data is referenced by the spooler and the spooler is canceled by the spooler.StoreddataSeeA data detection function for detecting the presence / absence of data in a predetermined mode, and a paper discharge command output function for outputting a paper discharge command to the printing apparatus when data in the predetermined mode is not detected by the data detection function To realizeThe predetermined size is smaller than the maximum data size output by the spooler.As a configuration.
[0006]
  In the invention according to claim 1 configured as described above, the data detection function is activated when a print job is canceled by the spooler, and data in a predetermined mode is added to the tail data in the spool data at the time of cancellation. Detect if there is any. Then, when no data of a predetermined mode is detected, a paper discharge command is output to the printing apparatus. In other words, in order to end the print job, the normal driver adds some data indicating the end of the print data in a predetermined manner at the end of the spool data, and when the printing is completed normally, the paper is properly discharged by the predetermined state data. Is done.
[0007]
  However, when the spooler cancels the print job, the transmission of the spool data stops halfway, and the data in the predetermined mode is not transmitted to the printing apparatus. Therefore, a paper discharge command is output when the predetermined mode data is not detected by the data detection function. Accordingly, even when canceling by such a spooler, the printing apparatus does not discharge the paper and does not remain stopped. Note that this data detection function is activated when the spooler cancels, so if the spooler happens to be running and the data is not sent for a while, the paper discharge command will not be output. Absent.
[0008]
  In addition, as described above, various modes are conceivable for configuring the data detection function to be executed at the time of cancellation by the spooler. For example, EndDocPort is configured as a module such as a language monitor and executed at the time of cancellation by the spooler. It can be realized as part of function processing.
[0009]
  As described above, in order to detect the presence / absence of data in a predetermined mode by the data detection function, the spool data reference function uses the tail of the spool data.From the predetermined sizeIt only has to be able to refer to the data. As its configuration, for example, it is possible to refer to data of the number of bits necessary for detecting the predetermined mode data. In this case, the tailFrom the predetermined sizeIt is preferable that data can be stored.
[0010]
  In other words, the spooler normally divides the print data into several files and outputs them to the printing apparatus when processing large print data. In this case, the last output data by chance may be less than the number of bits of the predetermined mode data. Therefore, the tail of the data that is divided and outputFrom the predetermined sizeIf the data is stored, it is possible to refer to the data corresponding to the number of bits of the predetermined mode data using the stored data and the last output data.Here, the predetermined size is a size smaller than the maximum data size of the file divided and output by the spooler.Further, there are various predetermined mode data to be referred to in this way. As a suitable example, data indicating the end of a print job given to the end of spool data by a normal driver can be used. .
[0011]
  In addition, the method for detecting the presence or absence of data in a predetermined mode in the transfer data and executing some processing according to the detection result is not limited to the paper discharge process in the printing apparatus described above, and is adopted in various methods. Is possible. Thereso,A medium in which a data identification program for identifying data in a predetermined mode that can be included in intermediate transfer data is recorded, and acquired by the intermediate transfer data acquisition function for acquiring intermediate transfer data and the intermediate transfer data acquisition function An intermediate transfer data reference function for referring to a predetermined position in intermediate transfer data, and a data mode determination function for determining whether or not data at a predetermined position referred to by the intermediate transfer data reference function is data in a predetermined mode To achieveCan also be considered.
[0012]
  Configured as aboveThenThe data of a predetermined mode that can be included in the intermediate transfer data is identified. That is, the intermediate transfer data is acquired and a predetermined position where the predetermined data can be described is referred to, and it is determined whether or not there is data in a predetermined mode at the position. As a result, it becomes possible to find data in a predetermined mode without scanning all transfer data, and the processing when executing some processing based on the data in the predetermined mode becomes very simple. Become faster.
[0013]
  Of course, the recording medium described above may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium that will be developed in the future. In addition, the duplication stages such as the primary duplication product and the secondary duplication product are equivalent without any question. Although different from the above medium, the communication line is used as a transmission medium when the communication method is used as a supply method, and the present invention is used.
  Further, even when a part is software and a part is realized by hardware, the idea of the invention is not completely different, and a part is stored on a recording medium and is appropriately changed as necessary. It may be in the form of being read.
[0014]
  As described above, the method for detecting the presence or absence of data in a predetermined mode by referring to the tail data in the spool data output from the spooler is realized in a substantial computer. In this sense, the present invention can be used as such a device. It can be easily understood that it is applicable. For this reason, the claim5~ Claim8In the invention according to this embodiment, the same operation is basically performed. Of course, such an apparatus may be implemented alone, or may be implemented together with other methods in a state of being incorporated in a certain device. Can be changed as appropriate.
[0015]
  In addition, it is obvious that such a paper discharge program has an invention in its procedure at the base of proceeding with processing according to such control, and it is easily understood that it can be applied as a method. it can. For this reason, the claim9~ Claim12In the invention according to this embodiment, the same operation is basically performed. In other words, the present invention is not necessarily limited to a tangible medium, and there is no difference that the method is effective.

DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
  FIG. 1 shows a schematic hardware configuration in a state where a printing apparatus is connected as a peripheral device to a computer, and FIG. 2 shows a schematic configuration when the present invention is realized as a paper discharge program composed of a plurality of modules in the computer. The figure is shown.
[0018]
  First, the schematic hardware configuration shown in FIG. 1 will be described. The computer 10 includes a CPU 11 serving as the center of arithmetic processing. The CPU 11 can access a ROM 13 and a RAM 14 such as a BIOS via a system bus 12. Further, a hard disk drive 15, a floppy disk drive 16 and a CD-ROM drive 17 as external storage devices are connected to the system bus 12, and an OS 20 and an application program (APL) 50 stored in the hard disk drive 15 are stored in the RAM 14. The CPU 11 appropriately accesses the ROM 13 and RAM 14 to execute the software. That is, various programs are executed using the RAM 14 as a temporary work area.
[0019]
  The serial communication I / O 19a is connected to input devices for operating a keyboard 41 and a mouse 42, and a display 18 for display is also connected via a video board (not shown). Further, it can be connected to the printing apparatus 30 via the parallel communication I / O 19b. Further, although the configuration of the computer 10 has been described in a simplified manner, a computer having a general configuration as a personal computer can be employed. Of course, the computer to which the present invention is applied is not limited to a personal computer. Although this embodiment is a so-called desktop computer, it may be a notebook computer or a mobile computer. Further, the connection interface between the computer 10 and the printing apparatus 30 is not limited to the parallel communication I / O 19b, and various connection modes such as USB connection and SCSI connection can be employed. It is the same even if there is.
[0020]
  In this example, each type of program is stored in the hard disk drive 15, but the recording medium is not limited to this. For example, it may be a floppy disk 16a or a CD-ROM 17a. The programs recorded on these recording media are read by the computer 10 via the floppy disk drive 16 and the CD-ROM drive 17 and installed in the hard disk drive 15. Then, it is read into the RAM 14 via the hard disk drive 15 to control the computer.
[0021]
  The recording medium is not limited to this, and may be a magneto-optical disk or the like. In addition, a non-volatile memory such as a flash card can be used as a semiconductor device, and the communication line becomes a transmission medium when accessing and downloading an external file server via a modem or communication line. The present invention is utilized. The printing apparatus 30 includes a CPU, firmware, and the like (not shown), and receives print data transmitted from the computer 10 via a predetermined I / O according to a program described in the firmware. The printing apparatus 30 executes printing based on the data while driving the head and the printing paper transport mechanism with a predetermined motor.
[0022]
  on the other hand,In the computer 10 according to the present embodiment, a printer driver (PRTDRV) 21, a spooler 22, and a language monitor 23 are incorporated in the OS 20. As shown in FIG.In the APL 50, a user can create a document, a drawing, or the like via the keyboard 41 or the mouse 42 and issue an instruction for executing printing on the printing apparatus 30. The PRTDRV 21 performs processing for converting data handled by the APL 50 into print data in accordance with a control signal from the APL 50, and the print data is output to the spooler 22. The PRTDRV 21 adds command data indicating the end of the print job with an “n” bit at the end of the data when outputting the print data.
[0023]
  The spooler 22 spools print data input from the PRTDRV 21 to the hard disk drive 15, and the spool data is further divided into predetermined capacities by the spooler 22, and the language monitor 23 is divided for each divided data. Passed to. The language monitor 23 outputs the received divided data to the printing apparatus 30 via the parallel communication I / O 19b. That is, the spooler 22 and the language monitor 23 cooperate to output print data in accordance with the printing progress status of the printing apparatus 30.
[0024]
  More specifically, the language monitor 23 is provided with various functions such as a StartDocPort function, a WritePort function 23a, an EndDocPort function 23b, and the spooler 22 executes an appropriate function in accordance with the processing, thereby performing printing processing. proceed. At the start of printing, the OpenPort function and the StartDocPort function are executed, and the two-way communication via the parallel communication I / O 19b is performed, for example, the printing device 30 that is the processing target of the PRTDRV 21 is designated by its device name or port name. A possible state is secured.
[0025]
  When the spooler 22 outputs the divided data to the language monitor 23, the Write Port function 23a is executed. For example, when the print data related to one print job is divided into four and output, the write port function 23a is executed four times, and the language monitor 23 sets the parallel communication I / O 19b for each divided data. Data is transmitted to the printing apparatus 30 via the network. In the Write Port function 23a according to the present embodiment, the last “n” bits of the divided data are stored in the RAM 14 as save data. If the divided input data is less than “n” bits, “n” bits of data are secured as save data from the back as the entire print data as will be described later.
[0026]
  At the end of the print job and when the spooler 22 cancels the print job, the language monitor 23 executes the EndDocPort function 23b and the ClosePort function, and performs processing such as releasing the parallel communication I / O 19b. In the EndDocPort function 23b, it is determined whether or not the save data matches the command data indicating the end of the print job. When the two do not match, the print paper is sent via the parallel communication I / O 19b. Output a reset command for ejection.
[0027]
  That is, when the EndDocPort function 23b is activated at the time of cancellation by the spooler 22, the spooler 22 interrupts the transmission of data, so that command data indicating the end of the print job is not input to the language monitor 23, and the command It cannot be output to the printing apparatus 30. In this case, since the save data does not match the command data indicating the end of the print job, a reset command is output and the printing paper is discharged. On the other hand, when the EndDocPort function 23b is activated at the end of the print job, the save data matches the command data indicating the end of the print job, so that no reset command is output.
[0028]
  FIG. 3 shows a flow of processing relating to the save data executed by the Write Port function 23a in such a configuration. Here, the divided data is divided into predetermined capacities by the spooler 22 and is equal in capacity for one print data before the last input divided data. However, since the print data cannot always be divided into equal volumes, the portion that cannot be divided equally is adjusted with the last divided data. Further, when the print job is canceled halfway by the spooler 22, data transmission is interrupted halfway. Therefore, the last input data or the data when the spooler 22 is canceled does not always have the same capacity as the previous divided data.
[0029]
  Therefore, in any case, each data actually input to the Write Port function 23a is referred to as buffer data, and its size is “m” bits. In the description of the figure, [x] is appended to the end of the buffer data to indicate the number of bits from the beginning of the buffer data. Therefore, in the notation of buffer data [x], “x” is an integer from “1 to m”. Similarly, [x] is also added to the end of the save data, indicating the number of the save data from the beginning, and in the notation of save data [x], the “x” is “1 to 1”. n "is an integer.
[0030]
  The Write Port function 23a is activated while being given the above buffer data and its size “m” as parameters, and in the flow shown in FIG. 3, the divided data satisfies the above “n” bits. A process for securing save data is performed so that appropriate determination can be performed later by the EndDocPort function 23b, including the case where there is no data. For this purpose, first, in step S100, it is determined whether or not the divided data size “m” is smaller than the command size “n” indicating the end of the print job.
[0031]
  If it is not determined in step S100 that the buffer data size “m” is smaller than the command size “n” indicating the end of the print job, the last “n” bits of the buffer data are obtained by the processing in steps S110 to S116. It is stored in the RAM 14 as save data. Specifically, in step S110, "1" is substituted for initialization to the counter "i" used for the processing, and buffer data [mn-i] is substituted for save data [i] in step S112.
[0032]
  here,The “mn + 1” th of the buffer data is the head of the last “n” bit of the buffer data. Therefore, the head of the save data [i] becomes the head of the tail “n” bit of the buffer data by the process of step S112.
[0033]
  In step S114, the counter “i” is incremented, and in step S116, it is determined whether or not the counter “i” is larger than the end command size “n”. Then, the processing from step S112 is repeated until it is determined in step S116 that the counter “i” is larger than the end command size “n”. That is, the tail data of the buffer data is stored for all the save data [1] to [n].
[0034]
  When it is determined in step S100 that the buffer data size “m” is smaller than the command size “n” indicating the end of the print job, the processing of steps S120 to S136 performs the tail of the previous buffer data, the current buffer data, In addition, save data for net “n” bits is secured. Here, the previous buffer data means that the write port function 23a is activated a plurality of times in order to execute the processing of each of the divided data, but the buffer data in the data activated immediately before the currently activated write port function 23a. Means.
[0035]
  Specifically, in step S120, "1" is substituted and initialized in the counter "i" used for the processing, and in step S122, the previous save data [m + i] is substituted in save data [i].. in frontThe previous save data [i] stored by the write port function 23a of the number of times is “n” bits. Therefore, the top of the save data is the “m + 1” th of the previous save data.
[0036]
  After the process in step S122, the counter “i” is incremented in step S124, and in step S126, it is determined whether or not the counter “i” is greater than “nm”. Then, the processing from step S122 to step S126 is repeated until it is determined in step S126 that the counter “i” is larger than “nm”. As a result, the previous saved data [m + 1] to [n] are newly secured as saved data [1] to [nm].
[0037]
  Further, in step S130, "1" is again substituted and initialized for the counter "i" used for the processing, and in step S132, the current buffer data [i] is substituted for the save data [n-m + i]. That is, after the save data [1] to [nm] generated in the above-described steps S122 to S126, the head of the current buffer data is substituted and assigned. In step S134, the counter “i” is incremented, and in step S136, it is determined whether or not the counter “i” is greater than “m”.
[0038]
  Then, the processing from step S132 to step S136 is repeated until it is determined in step S136 that the counter “i” is larger than “m”. As a result, the buffer data [1] to [m] are newly secured as save data [n−m + 1] to [n]. That is, the above-described processing secures the current buffer data as a sum of the necessary number of bits at the end of the previous save data and the current buffer data. As a result, the save data becomes “n” bits.
[0039]
  FIG.Shows the flow of processing relating to the comparison between the save data and the end command executed by the EndDocPort function 23b in such a configuration. In step S200, the save data stored in the RAM 14 is referred to, and the end command data that the language monitor has by default is compared with the reference data. If it is determined in step S200 that the two match, processing such as attaching end command data or the like is not particularly executed, and the function of the normal EndDocPort function 23b is executed.
[0040]
  If it is not determined in step S200 that the two match, a reset command for discharging the printing paper is output via the parallel communication I / O 19b in step S210. The EndDocPort function 23b is activated when the print job ends and when the print job is canceled in the spooler 22 as described above. At the end of the print job, since the save data is an end command by the processing of the above-described Write Port function 23a, the end command is output to the printing apparatus 30 without performing any processing in the EndDocPort function 23b.
[0041]
  On the other hand, when the print job is canceled in the spooler 22, the print data is not output to the end, and the save data acquired by the processing of the above-described Write Port function 23a is not an end command. However, since the reset command is output to the printing apparatus 30 by the processing in step S210, the printing paper is appropriately discharged when the printing apparatus 30 prints halfway through the printing paper.
[0042]
  Next, a specific example of print job processing realized by the above configuration and flow will be described.Here, an example in which the print job is canceled by the spooler 22 is shown.When a print instruction or the like is given by the APL 50, the PRTDRV 21 executes the predetermined processing and outputs the processing data to the spooler 22 in a collective state. At this time, the PRTDRV 21 attaches an end command to the end of the print data.
[0043]
  When the print data is given, the spooler 22 spools the print data and divides the print data into predetermined capacities, and outputs them in the order of the print data sequence..
[0044]
  In the language monitor 23, the write port function 23a is executed each time the spooler 22 outputs divided data. In this specific example, since the buffer data size is larger than the end command size in the processing of the second divided data, the tail “n” bit of the buffer data is set as the save data [i] by the determination in step S100. Since the first and second divided data acquired by the language monitor 23 are output to the parallel communication I / O 19b, the printing apparatus 30 is based on the first and second divided data. Printing is performed.
[0045]
  When the spooler 22 cancels the print job as described above, the EndDocPort function 23b is activated on the language monitor 23. Here, since the save data is not the end command, the reset command is output in step S210 after the determination in step S200. Accordingly, in the printing apparatus 30, the printing paper is discharged after the printing based on the first and second divided data is executed, and when the spooler 22 cancels, the printing of the printing apparatus 30 stops halfway and the printing paper is discharged. It never gets sent halfway.
[0046]
  Furthermore, as another specific exampleA case where the print job is executed to the end without being canceled by the spooler 22 and the end of the divided data is less than the end command size will be described. in this case,Similar to the above example, the PRTDRV 21 executes the predetermined processing when the APL 50 gives a print instruction or the like, and outputs to the spooler 22 in a bundled state with an end command added to the end of the processing data. .
[0047]
  When the print data is given, the spooler 22 spools the print data and divides the print data into predetermined capacities, and outputs them in the order of the print data sequence..In the language monitor 23, the write port function 23a is executed each time the spooler 22 outputs divided data. In a specific example in which the spooler 22 divides the input print data into four, and the fourth divided data is less than the end command size, the buffer data size in the fourth divided data processing is larger than the end command size. Since it is small, the save data of the third divided data is used by the discrimination in step S100, and the data of the number of bits necessary in the processing of steps S120 to S126 is stored in order from the head of the save data [i]. In the process of S136, the fourth buffer data is added to obtain save data [i].
[0048]
  In this specific example, since the print job process proceeds without canceling in the spooler 22, the language monitor 23 outputs all of the first to fourth divided data to the parallel communication I / O 19b. To do. Accordingly, the printing apparatus 30 properly executes printing including the printing paper discharge process. When the spooler 22 outputs all of the data up to the fourth divided data, the enddocport function 23b is executed in the language monitor 23. However, in step S200 of the enddocport function 23b, it is determined that the save data matches the end command. The reset command is not output.
[0049]
  As described above, in the present invention, the tail data in the spool data is referred to when canceling by the spooler, and a paper discharge command is output to the printing paper when data in a predetermined mode is not detected in the reference tail data. . Therefore, even when printing cancellation by the spooler is performed, the printer can discharge the printing paper without bothering the user.
