Description

  The present invention includes a printer with a buzzer that can sound a buzzer at a predetermined timing in conjunction with a printing operation by sending a command from a host device, a method for controlling a printer with a buzzer, and a printer with a buzzer. The present invention relates to a printer system control method.

  As a printer with a buzzer, there is a printer whose buzzer sounding timing is controlled by sending a command from a host device, and a printer which has a buzzer sounding timing set in advance in the printer itself.

  As the latter printer with a buzzer, there is one disclosed in Patent Document 1. In the printing apparatus disclosed herein, when an abnormal state such as a cover open, a paperless printing stop, a recoverable error or an unrecoverable error occurs during operation, the printing apparatus is configured to sound a buzzer in a predetermined manner. The ringing timing is set in advance in itself. In addition, a sound notification setting command for designating whether or not to sound a buzzer sound, the type of buzzer sound, the number of ringing, and the like is received from the host device together with a print command and a line feed command. Furthermore, when a sound stop command is received from the host device, an interrupt process can be executed based on the sound stop command to stop the buzzer.

JP 2001-166904 A

  In the printing apparatus disclosed in Patent Document 1, a buzzer can be sounded with detection of an abnormal state as a trigger, but a print job is being executed, such as a buzzer sound for each page break operation or paper cut operation. It has not been proposed to sound a buzzer with the execution of a predetermined control command as a trigger. In this printing device, since the conditions for sounding the buzzer are stored in advance on the printing device body side, it is not necessary to send a buzzer command from the host device when the buzzer sound is always sounded with the same setting. When changing the trigger condition, it is necessary to change the setting on the printer body side by transmitting a sound notification setting command from the host device each time. Therefore, if you want to sound the buzzer with a complicated setting such as sounding the buzzer only when a page break is performed for each specified number of pages, the sound notification setting command must be sent and executed in accordance with the timing for sounding the buzzer. The process becomes complicated.

  If you want to notify the user by sounding the buzzer at a state other than when a printer error has occurred, for example, at the end of printing, at a page break, or at paper cut, the buzzer can be activated for each print job as desired by the user. It is desirable to be able to easily change whether or not to ring. For this purpose, it is conceivable to add a buzzer command to the print command transmitted from the host device side in correspondence with the timing at which the buzzer is desired to ring. For example, as a print command transmitted from the host device to the printer, a buzzer command is added to the page break command indicating the page break position in the print data or a print page command indicating the end of the print data after the print data is added. What added is used.

  However, in the method of inserting a buzzer command at each position (order) in the print command from the host device, the buzzer command included in the print command should be sounded on the printer side. Since the buzzer is sounded by analyzing the command each time (in order), there may be a delay in the timing at which the buzzer actually sounds. Further, since a buzzer command is required every time the buzzer sounds, the structure of the print command and the processing on the printer side become complicated.

  For example, when a buzzer command is received after printing is finished, the printer detects the print end command and executes a series of print end processing operations, and then executes the buzzer command to sound the buzzer. The print end process operation includes a process for returning the head carriage to the home position, a paper feed process, a paper cut process, and the like, and a head cleaning process is automatically activated when a predetermined condition is satisfied. For example, when the head cleaning process is started, the buzzer sounds after waiting for the end of the head cleaning process. Therefore, the buzzer sounding time for notifying the user of the printing end time is larger than the actual printing end time. There is also a problem that it is greatly delayed.

  In view of the above, the problem of the present invention is that the buzzer can be sounded without causing a delay at a predetermined timing by command transmission from the host device side, and one command transmission can be performed. An object of the present invention is to propose a control method for a printer with a buzzer, a control method for a printer system, and a printer that can make a buzzer sound at various timings by simply performing the buzzer.

In order to solve the above problems, a printer control method of the present invention includes:
A method for controlling a printer with a buzzer,
Print control commands;
Receiving a buzzer setting command for controlling the sounding of the buzzer;
When the print control command includes a predetermined command specified by the buzzer setting command, the buzzer is caused to ring at a predetermined timing and in a manner triggered by the execution of the predetermined command.

The control method of the printer system of the present invention includes:
A print control command is received from the host device, and a buzzer setting command for controlling the sounding of the buzzer is received prior to the print control command.
When the print control command includes a predetermined command specified by the buzzer setting command, the buzzer is caused to ring at a predetermined timing and in a manner triggered by the execution of the predetermined command.

  As described above, according to the present invention, based on the buzzer setting command, the buzzer can be sounded with the execution of a predetermined command (trigger command) in the print control command as a trigger. Thereby, as long as the setting by the buzzer setting command is valid, the buzzer can be sounded by the number of times of execution of the trigger command with one command, so that the data structure of the print command can be simplified. Further, since it is not necessary to analyze and execute the buzzer sound generation command as many times as the buzzer is sounded, it does not take a processing time to analyze and execute the buzzer sound generation command each time the buzzer is sounded. Therefore, the time lag until the buzzer sounds can be eliminated or shortened. In addition, it is possible to change settings such as a command for triggering a buzzer and a buzzer ringing mode for each print job. The print control command may include not only the control command but also print data.

In the printer control method of the present invention, a print command including a command group in which the buzzer setting command is arranged before the print control command is received,
It is determined whether or not the buzzer setting command is included in the command group received prior to the print control command. When the buzzer setting command is included, the command group is designated by the buzzer setting command. Storing and holding the predetermined command;
When the predetermined command included in the print command is detected, a process based on the predetermined command is executed, and the buzzer is sounded at a timing and a mode specified by the buzzer setting command.

In the control method of the printer system of the present invention,
A print command including a command group in which the buzzer setting command is arranged before the print control command is transmitted from the host device to the printer.
The printer determines whether the buzzer setting command is included in the command group received prior to the print control command, and if the buzzer setting command is included, the buzzer setting command Storing and holding the predetermined command specified by
When the predetermined command included in the print command is detected, a process based on the predetermined command is executed, and the buzzer is sounded at a timing and a mode specified by the buzzer setting command.

  In the present invention, since the buzzer setting command is arranged before the print control command as described above, if the buzzer control command is included, it is determined that the buzzer control command is present, and the predetermined b designated by the buzzer control command. After the command (trigger command) is stored, the print control command can be analyzed and printed. Therefore, the buzzer can be reliably sounded with the execution of a predetermined command during the printing process as a trigger.

  In the printer control method and the printer system control method of the present invention, the print command is a page break command for designating a page break process and / or a print end command for designating a process to be executed after the print process is completed. In the buzzer setting command, the page break command and / or the print end command may be designated as the predetermined command. The print command may include a plurality of page break commands, and in the buzzer setting command, only a part of the page break commands among the plurality of page break commands may be designated as the predetermined command. In this way, the buzzer can be sounded in accordance with the page break timing or the print end timing. In addition, when the buzzer is sounded at the page break timing, it is possible to set the buzzer to sound only for the page you want to ring, for example, every predetermined page or at the last page break. is there.

  In the present invention, at least one of the ringing pattern, volume and frequency of the buzzer may be designated by the buzzer setting command. In this way, the buzzer can be sounded in a different manner for each print job.

  The printer of the present invention includes a buzzer and a control unit that controls ringing of the buzzer, and the control unit executes the above-described printer control method.

  According to the present invention, based on the buzzer setting command, the buzzer can be sounded with the execution of a predetermined command (trigger command) in the print control command as a trigger. Thereby, as long as the setting by the buzzer setting command is valid, the buzzer can be sounded by the number of times of execution of the trigger command with one command, so that the data structure of the print command can be simplified. Further, since it is not necessary to analyze and execute the buzzer sound generation command as many times as the buzzer is sounded, it does not take a processing time to analyze and execute the buzzer sound generation command each time the buzzer is sounded. Therefore, the time lag until the buzzer sounds can be eliminated or shortened. In addition, it is possible to change settings such as a command for triggering a buzzer and a buzzer ringing mode for each print job.

1 is a block diagram of a printer to which the present invention is applied. FIG. 2 is an explanatory diagram illustrating a data structure of a print command in the printer of FIG. 1. 3 is a flowchart when a print job is executed in the printer of FIG. 1.

  Embodiments of a printer system of the present invention will be described below with reference to the drawings.

(overall structure)
FIG. 1 is a block diagram showing a schematic configuration of a printer system S including an inkjet buzzer-equipped printer 1 and a host device 2 to which the present invention is applied. As shown in FIG. 1, the printer 1 includes a control unit 10 that controls each unit of the printer, a printing mechanism 20 that performs a printing operation on recording paper in response to a control signal from the control unit 10, and a host device 2. And a communication unit 30 that is an interface unit for performing communication, and a buzzer 40 that rings based on a control signal from the control unit 10. In addition, the printer 1 includes a power supply unit and an operation unit (not shown).

  The control unit 10 includes an arithmetic processing unit such as a CPU, a flash ROM or EEPROM that stores various programs and data necessary for control, and a storage unit such as a RAM that functions as a work area during processing by the CPU. 11 is provided. Commands and print data from the host device 2 are input to the control unit 10 via the communication unit 30. The communication unit 30 in the printer 1 is configured to be connectable to the host device 2 by wireless communication using a wireless LAN adapter or the like, or wired communication using a USB cable, a LAN cable, or the like.

  The printing mechanism 20 includes a recording head, a carriage on which the recording head is mounted, a carriage feeding mechanism that moves the carriage in the paper width direction, a recording paper cutting device that cuts the recording paper, and a drive mechanism thereof. The printing mechanism 20 includes a paper feeding mechanism for transporting recording paper such as roll paper set in the printer 1 along a predetermined transport path. The printing mechanism 20 includes a driving circuit such as a gate array and a driving motor. When a control signal from the control unit 10 is input to the driving circuit, a motor driving current is generated and supplied to the driving motor. The output of the drive motor is transmitted to a paper feed mechanism or a drive mechanism for driving the recording head, whereby each mechanism operates. While the recording head is operating, the control unit 10 operates the paper feed mechanism in conjunction with the printing operation to move the recording paper. When the printing operation by the recording head is finished, paper feeding for discharging the printed recording paper to the outside of the printer 1 is performed.

  For the buzzer 40, for example, a piezoelectric buzzer is used. The control unit 10 transmits a drive signal having a predetermined drive pattern to the buzzer 40 at a predetermined timing. The buzzer 40 rings at a predetermined timing and ringing pattern (the ringing time length, ringing frequency, ringing interval, etc.) according to the drive signal from the control unit 10. Further, the buzzer 40 can adjust the volume, frequency, sound quality (sound type), and the like of the buzzer sound according to the drive signal from the control unit 10. Based on the execution of a trigger command set by a buzzer setting command, which will be described later, the control unit 10 generates a buzzer driving signal for causing the buzzer 40 to ring in a mode (ringing pattern, volume, frequency, etc.) and timing specified by the command. 40.

(Print control of printer)
Next, the control at the time of executing a print job in the printer 1 having the above configuration will be described. FIG. 2 is an explanatory diagram showing a data structure of a print command transmitted from the host apparatus 2, and FIG. 3 is a flowchart when a print job is executed. As shown in FIG. 2, the print commands transmitted from the host device 2 to the printer 1 are four types of data: a print setting command A, a buzzer setting command B, a print control command C, and a print end command D. The data structure is lined up. The contents of each data will be described below.

(1) Print setting command A
The print setting command A is a paper setting command for setting a recording paper type, a print area, a printing method, and the like in this print job, after printing of each page, or after printing of a specific page such as the last page. Cut-on / off setting command for specifying whether or not to execute automatic cut processing for automatically cutting printing paper with a recording paper cutting device, platen strike prevention processing for preventing printing even when there is no recording paper Includes a platen strike prevention on / off command for setting whether to perform printing, a printing direction setting command for setting whether to perform unidirectional printing or bidirectional printing when moving the carriage in the case of a serial head, etc. Yes.

(2) Buzzer setting command B
The buzzer setting command B is a command for setting conditions and a sounding method for sounding the buzzer 40. The buzzer setting command B includes a command for specifying a command to be used as a trigger command for causing the buzzer 40 to ring out of commands included in a print control command to be described later. Further, the buzzer setting command B may include a command for designating at what timing or in what manner the buzzer 40 is sounded based on the execution of the trigger command. For example, it is possible to include a command for designating a ringing pattern such as a ringing time length, ringing frequency, ringing interval, and the like, a sound frequency, sound quality (sound type), volume, and the like.

(3) Print control command C
The print control command C includes print data C1 indicating print contents such as characters and graphics actually printed on recording paper, and a page break command C2 for controlling page break processing performed after printing each page. . That is, the print control command C has a structure in which the print data C1 and the page break command C2 are alternately arranged by the number of print pages. The page break command C2 includes a cleaning command for automatically cleaning the nozzles of the recording head at the time of page break, a paper feed command for feeding the recording paper by the margin at the rear end of the page, and recording at the page rear end position. It may include a cut command for cutting the paper. Execution of the cut command can be controlled by a cut-on / off setting command included in the print setting command A described above. For example, by specifying a page on which a cut command is executed or a page on which a cut command is not executed with a cut-on / off setting command, it is possible to control to execute only the cut command on the specified page. Note that the print data C1 may include commands for decorating characters and graphics.

(4) Print end command D
The print end command D is a command for performing processing for ending the print job after printing on the recording paper is completed. The print end command D is a command for initializing the contents set by the print setting command A, a command for initializing the contents set by the buzzer setting command B, and notification of the end of the print job to each part of the printer 1 or the host device 2. Job end command to be executed.

  When the control unit 10 of the printer 1 receives a print command in which the above commands and print data are arranged from the host device 2, the control unit 10 analyzes the command and print data included in the print command. Then, it is determined whether or not the buzzer setting command B is included in a predetermined data block in the print command (S1). In this embodiment, since the buzzer setting command B is stored in the data block immediately before the print control command C, the control unit 10 analyzes this data block and determines the presence or absence of the buzzer setting command B.

  When the print command includes the buzzer setting command B, the control unit 10 stores the fact that the buzzer setting command B is received in the built-in storage unit (S2). Further, in this process, the control unit 10 detects the buzzer 40 ringing condition specified by the buzzer setting command B in the built-in storage unit 11, that is, which command is the trigger command and the trigger command. The buzzer sounding mode and sounding timing are memorized. In the buzzer setting command B, for example, a page break command C2 is designated as a trigger command. In addition, as the sounding timing of the buzzer 40, the end point of the recording paper auto-cut process executed during the page break process of each page is designated. Moreover, it is designated as a ringing mode that a sound of a predetermined volume and frequency is sounded only once with a predetermined length. Therefore, the control unit 10 stores these ringing conditions in the storage unit 11. On the other hand, if the buzzer setting command B is not detected in step S1, the control unit 10 proceeds to the printing process step (S3) without storing the buzzer setting command B in the storage unit 11.

  Although not shown in FIG. 3, the control unit 10 analyzes the print setting command A before executing the print processing step, and stores the setting contents by the buzzer setting command B, similarly to the case where the setting contents are stored. The setting content by the print setting command A can be stored in the storage unit 11. The control unit 10 performs print control described below according to the settings specified by the print setting command A and the buzzer setting command B.

  The control unit 10 sequentially analyzes the print control command C in which the print data C1 and the page break command C2 are alternately arranged by the number of print pages, and sequentially executes processing according to the analysis content. First, the control unit 10 analyzes the print data C1 of the first page, develops it into print data for the recording head, and stores it in the image buffer. Based on the developed print data, a drive signal is sequentially given to the head control circuit and the paper feed motor control circuit to execute the printing operation (S3). The control unit 10 determines whether or not the page break command C2 is detected at a predetermined timing while sequentially analyzing and executing the print data C1 of the first page (S4). When the page break command C2 is detected (S4: Yes), the process proceeds to page break process execution (S5a to S5c). On the other hand, if the page break command C2 is not detected (S4: No), the process returns to step S3, and the analysis and printing operation of the E print data C1 are continued as they are.

  In the page break process, three processes are executed in this order: a cleaning process based on a cleaning command (S5a), a paper feed process based on a paper feed command (S5b), and an automatic cut process based on a cut command (S5c). When the control unit 10 proceeds to the page break process, the determination result of the presence / absence of the buzzer setting command B in step S1 at the end of execution of the auto cut process specified as the ringing timing of the buzzer 40 in this print job. Is confirmed (S6). In addition, the control part 10 precedes the auto cut process (S5c) in the page break process when the setting that the auto cut process (S5c) is not executed is made by the cut on / off setting command described above. Then, the process is changed so that the step S6 is performed at the end of the execution of the paper feed process (S5b).

  When the storage unit 11 stores the buzzer setting command B as being present (S6: Yes), the control unit 10 sounds the buzzer 40 in a manner specified by the buzzer setting command B. That is, the control part 10 produces | generates the drive signal for driving the buzzer 40 in the designated aspect, gives it to the buzzer 40, and rings the buzzer 40 (S7). On the other hand, if it is not stored in the storage unit 11 that the buzzer setting command B is present (S6: No), the control unit 10 returns to the step S3 without ringing the buzzer 40 and continues the process.

  The control unit 10 repeats the printing operation and the page break operation for the predetermined number of print pages, and checks the determination result of the presence or absence of the buzzer setting command B each time the automatic cut process in the page break operation of each page ends. (S6) If the buzzer setting command B is present, the buzzer 40 is sounded (S7). Then, after the page break operation for the last page is performed, processing for initializing the contents set by the print setting command A and the buzzer setting command B is performed based on the print end command D. That is, the setting content stored in the storage unit 11 is returned to the initial setting. Then, the end of the print job is notified to each unit of the printer 1 to put each unit of the printer 1 in a print standby state, and a signal for notifying the host device 2 of the end of the print job is output. If the next print data has already been received, the print job is continuously executed without entering the print standby state.

(Effect of this embodiment)
As described above, based on the buzzer setting command B, the printer 1 can sound the buzzer 40 using the page break command C2 in the print command as a trigger. That is, by inserting the buzzer setting command B before the print control command C, the buzzer 40 can be sounded using all the page break commands C2 included in the print command as a trigger. Therefore, since it is not necessary to insert a buzzer sound generation command for each page break in the print command, the data structure of the print command can be simplified. In addition, since it is not necessary to analyze the buzzer sound generation command for each page break process, the processing load for generating the buzzer sound can be reduced. Therefore, the time lag between the time when the buzzer 40 is desired to be sounded (when the trigger command is detected) and the actual time when the buzzer is sounded can be eliminated or shortened. In addition, it is possible to freely change the setting of the command and the buzzer sounding mode that trigger the buzzer for each print job.

(Modification example)
(1) In the above embodiment, the page break command C2 for all pages is set as a trigger command for causing the buzzer 40 to sound, but only the page break command C2 for a specific number of pages is set as a trigger command. May be set. For example, only the page break command C2 every n pages (n: natural number) may be set as a trigger command. In this case, when the page break command C2 is detected, the control unit 10 accumulates the detected number and determines whether or not the detected number is a multiple of n. Only when the number is a multiple of n, processing for confirming the determination result of the presence / absence of the buzzer setting command B is performed (S6). In this way, the buzzer 40 can be sounded every n pages. Similarly, when the buzzer 40 is sounded only after the printing of the last page is completed, the process proceeds to steps S6 to S7 only when it is detected that the number of detected page break commands C2 indicates the number of the last page. Alternatively, when a print end command is detected, the process proceeds to steps S6 to S7.

(2) In the above embodiment, the page break command C2 is set as a trigger command, but the print end command D may be set as a trigger command. Further, both the page break command C2 and the print end command D may be set as trigger commands.

(3) Notification means other than the buzzer 40 may be operated by a command similar to that of the buzzer 40 described above. For example, a lamp setting command for setting a condition and a lighting method for lighting a lamp provided in the printer 1 body, a display setting command for setting a condition and a display method for performing a predetermined display on the display unit of the printer 1, May be included in the print command in the same manner as the buzzer setting command B.

(4) In the above embodiment, the buzzer setting command B is included in the data block immediately before the print control command C in the print command. However, the data block is not limited to this position as long as it is before the print control command C. Further, the buzzer setting command B may not be included in the print data but may be transmitted separately from the print command before the print command is transmitted.

(5) In the above-described embodiment, a predetermined command is set as a trigger command. However, predetermined print data may be set as a trigger command. For example, the buzzer 40 may be sounded when a character such as the last “yen” of the receipt is printed.
