Description

The present invention relates to a print system and a program including a host computer and a printer that executes printing based on a print job transmitted from the host computer.

2. Description of the Related Art Conventionally, a system is known in which a host computer and a printer are connected and print data generated by the host computer is transmitted to the printer to perform print processing. For example, in a POS system used in a supermarket or a retail store, print data is generated from product data based on product information input by an operator (store clerk) by a POS terminal computer, and the print data is printed by a printer (printing device). Send to. The printer prints receipts, coupons, and the like based on the received print data. Then, the printed receipt or coupon is cut to an appropriate length and discharged from the receipt conveyance path (for example, Patent Document 1).
reference).

JP 2005-222310 A

However, in the POS system as described above, the operator cannot determine when the receipt or coupon printing process is completed. In particular, coupons are often issued based only on the specified product, so the operator knows how many coupons will eventually be issued and determines when the printing process will be completed. It is difficult to do. For this reason, when there are many customers and there is not enough time, the operator tries to take out the receipt or coupon before the printing process is completed, especially before the paper is cut. It may tear off. As a result, a paper jam of the printer occurs, and there is a problem that the printing service is stopped until the restoration operation is completed, and a receipt or coupon cannot be issued.

SUMMARY An advantage of some aspects of the invention is that it provides a print system and a program that allow an operator to easily recognize completion of print processing.

The print system control method of the present invention generates a print job having print data, a print control command, and a print job ID based on a print request, and generates a notification control command including the print job ID in a host computer. The generated print job and notification control command are asynchronously transmitted from the host computer to the printer. The printer receives the print job and notification control command asynchronously, and receives the print job at the printer. When the print job ID included in the print job is acquired and the notification control command is received by the printer, the transmitted notification control command is stored in the storage unit of the printer, and printing based on the print job is executed. when the printed matter is completed is issued, the print job ID and the one obtained It is determined whether or not a notification control command having a print job ID to be stored is stored in the storage unit, and a notification control command having a print job ID that matches the print job ID included in the print job exists in the storage unit. If it is, the notification means of the printer is notified.
The print system of the present invention includes a control unit that generates print data, a print control command, a print job having a print job ID, and a notification control command including the print job ID, a print job transmission unit that transmits the print job, and A host computer having a notification control command transmission unit that transmits a notification control command asynchronously with a print job, a storage unit that stores the notification control command transmitted from the host computer, a printing unit that executes printing based on the print job, and a notification Notification means for notifying based on a control command, notification control command having a print job ID that matches a print job ID included in the print job when printing based on the print job is completed by the printing means and a printed matter is issued Notification determination means for determining whether or not is stored in the storage means, And a printer having a control unit that informs the notification means when a notification control command having a print job ID that matches the print job ID included in the print job is present in the storage means. It is characterized by.

According to this configuration, the print job including the print data and the notification control command including the notification command are asynchronously transmitted from the host computer to the printer. Upon receiving these, the printer stores the notification control command in its own storage area (storage means) and executes a print job. When the printer detects that the print job is completed, the printer determines whether or not a notification control command including the same print job ID as the print job ID of the print job exists in the storage area. . When a notification control command including the print job ID exists in the storage area, the notification unit notifies the user. Thereby, since the operator can grasp the completion of the print job, for example, it is possible to recognize that the issue processing (print job) of a printed matter such as a receipt or a coupon has been completed. For this reason, by educating the operator to take the printed material after the notification by the notification means, it is attempted to take out the printed material before the printing process is completed (particularly before the paper is cut) and tear the printed material. Can improve. As a result, the printer can be prevented from being jammed due to the tearing, and the operating rate of the print service can be improved. In addition, since the print job and the notification control command can be transmitted asynchronously, for example, when the print job is being processed, when the print job transmission is delayed for some reason, or when the printer has an error. Even when the job cannot be transmitted, the notification control command can be transmitted without being affected by the status of the print job. Further, on the printer side, by receiving the notification control command asynchronously with the print job and recording it in the storage area, it is possible to immediately execute the processing related to notification after the print job is completed. In addition, as an alerting | reporting means, you may alert | report auditorily with a sound, or you may make it lightly alert | report by lighting a lamp | ramp.

According to the printing system control method of the present invention, when the printer completes printing of a print job, a notification control command having a print job ID that matches the print job ID included in the print job exists in the storage unit. If not, it is preferable to update the status for the print job ID included in the print job for which printing has been completed to “print processing completed” .
Further, according to the printing system control method of the present invention, when the printer receives the notification control command, the print job ID stored in the job history storage means matches the print job ID included in the received notification control command. If the print job ID stored in the job history storage means matches the print job ID included in the received notification control command, the print job ID stored in the job history storage means It is preferable that the status is determined, and when the status is the completion of the printing process , the notification means of the printer immediately notifies.
The printing system according to the present invention includes a print job ID storage unit that stores a print job ID of a print job that is being printed by the printing unit, and stores the acquired print job ID. A job history storage unit that stores a print job ID of a print job that has been completed, and when execution of printing of the print job in which the print job ID is stored in the print job ID storage unit is completed, When the notification control command including the matching print job ID is not recorded in the storage unit, it is preferable to store the print job ID stored in the print job ID storage unit in the job history storage unit.

According to this configuration, when the notification control command is received, it is determined whether or not the print job ID included in the notification control command is recorded in the execution history.
An immediate notification is performed based on the notification control command. Thereby, for example, even when the notification control command is delayed for some reason, it is possible to reliably notify the operator that the print job has been completed, that is, the printed matter has been issued.

In these cases, the host computer further includes a print job determination unit that determines a print job that satisfies a predetermined condition, and the notification control command transmission unit transmits only the notification control command corresponding to the predetermined print job to the printer. Is preferred.

According to this configuration, only the completion of a specific print job can be notified. For example, 1
When a plurality of printed materials are issued to a customer, the operator notifies only the completion of the print job for issuing the last printed material, so that all the printed materials issued before the notification are for one customer. And forgetting to hand over the printed matter can be prevented. Further, for example, by notifying only when a print job for issuing a special printed matter such as a winning coupon is completed, the operator can easily recognize that the special printed matter has been issued.

In these cases, it is preferable that a notification pattern storage unit that stores a plurality of notification patterns in advance is further provided, and the notification command includes information for designating one notification pattern from among the plurality of notification patterns. .

According to this configuration, by storing a plurality of notification patterns on the printer side in advance, it is only necessary to transmit only information specifying the notification pattern from the host computer to the printer.
Transmission of the notification pattern itself becomes unnecessary. Thereby, the traffic which concerns on transmission of an alerting | reporting pattern can be reduced.

In these cases, it is preferable that the notification means of the printer is a sounding means that sounds a sound .

According to this configuration, it is possible to notify the operator of the completion of the print job by ringing with an electronic sound. Thereby, for example, even when the operator is dealing with the customer and cannot see the printer, it is possible to easily grasp the completion of the print job, that is, the printed matter is issued.

The POS system of the present invention generates print data, a print control command, a print job for issuing a coupon having a print job ID, and a notification control command including the print job ID based on a request from the POS application. A host computer having a control unit for transmitting, a print job transmitting unit for transmitting a print job, and a notification control command transmitting unit for transmitting a notification control command asynchronously with the print job, and a memory for storing the notification control command transmitted from the host computer Means, printing means for executing printing based on the print job and printing coupons, notifying means for notifying based on the notification control command, when printing based on the print job is completed by the printing means and the printed matter is issued Print job I that matches the print job ID included in the print job A notification determining unit for determining whether or not a notification control command having the print job ID stored therein is stored in the storage unit, and a notification control command having a print job ID that matches the print job ID included in the print job by the notification determination unit. And a printer having a control unit that causes the notification means to notify the user of the presence of the printer.

By using this, it is possible to provide a POS system that can notify the completion of a print job.

It is a control block diagram of a host computer and a printer. 10 is a flowchart illustrating a procedure for generating a print job and a ringing control command. 6 is a flowchart for describing an operation procedure when the printer receives a print job. It is a flowchart explaining the operation | movement procedure when a printer receives a ringing control command.

Hereinafter, a print system according to the present embodiment will be described with reference to the accompanying drawings.
The printing system according to the present embodiment is a system that allows an operator to easily recognize completion of printing processing. Hereinafter, in the present embodiment, a case will be described in which coupons are targeted as printed matter, and notification is made by ringing with an electronic sound as notification means.

FIG. 1 is a diagram showing a device configuration of a print system 1 according to the present invention. As shown in the figure, the print system 1 of the present embodiment is based on a print job and a host computer 2 that transmits a ringing control command (notification control command) corresponding to the print job, and a print job received from the host computer 2. And a printer 3 having a function of sounding based on a sounding control command.

The host computer 2 is a computer for managing the printer 3 and transmits a print job to the printer 3 (outputs a print instruction). When the host computer 2 receives a request for issuing a coupon or the like from a POS application (not shown), the business application 31 (to be described later) generates a print job based on the request and assigns a print job ID to each print job. Then, the print job is managed based on the print job ID, and the print job is transmitted to the printer 3.

Further, after generating the print job, the host computer 2 generates a sound control command for sounding the buzzer 46 (notification means, see FIG. 2) of the printer 3 as necessary. In this ringing control command, a print job ID for ringing the buzzer 46 of the printer 3 after completion of printing and a ringing pattern (notification pattern, details will be described later) of the buzzer 46 are defined. Then, the host computer 2 transmits this sounding control command to the printer 3 so that the buzzer 46 can sound at a predetermined timing (after completion of printing) and a predetermined sounding pattern.

On the other hand, the printer 3 is an ink jet printer 3 that uses a plurality of types of color inks as a recording material, performs image recording (multi-color printing) on a recording medium, and issues coupons and the like. As shown in FIG. 1, in the printer 3, a power switch 12, a roll paper cover 13, and a mounting portion opening / closing cover 14 are arranged in this order from the left side on the front surface of a printer case 11 including a front upper panel 11a and a case cover 11b. A paper discharge port 15 for discharging the roll paper faces above the roll paper cover 13. A plurality of LED lamps 16 for notifying the operator (user) of the state of the printer 3 are provided above the power switch 12. The roll paper cover 13 is loaded with roll paper (not shown) in which the paper is wound in a roll shape, and an ink cartridge (not shown) is installed inside one of the mounting portion opening / closing covers 14. Has been.

When the printer 3 receives a print job from the host computer 2, based on the print job, the printer 3 performs color printing of a desired image such as a character or a pattern on the paper and prints paper (such as a coupon) printed from the paper discharge port 15. Is discharged. Further, the printer 3 receives the ring control command from the host computer 2 and controls the ring of its own buzzer 46 based on the ring control command. When the printing process of the print job is completed, the printer 3 sounds an electronic sound from the buzzer 46 based on the ringing pattern of the ringing control command including the print job ID of the print job, and the printing process is completed for the operator. Effect, that is, paper outlet 1
5 that the coupon has been discharged. By notifying by ringing by electronic sound,
For example, even when the operator is dealing with the customer and the printer 3 cannot be visually recognized, it is possible to easily grasp the completion of the print job, that is, that the coupon has been issued.

Note that as a means for notifying completion of a print job (coupon discharge from the paper discharge port 15), the sound control command may be used as described above to be notified audibly by means of an electronic sound from the buzzer 46. Alternatively, the LED lamp 16 described above may be lit (blinks) to notify visually.

Next, the host computer 2 and the printer 3 constituting the print system 1 according to the present invention will be described with reference to the control block diagram of FIG.

The host computer 2 includes a CPU 21 (Central Processing Unit), a ROM 22 (Rea
d Only Memory), RAM 23 (Random Access Memory), HDD 24 (Hard Disk Drive
), An input device 25 and a communication interface 26. HDD 2
4 is copied to the RAM 23 at the time of startup, and data stored in the RAM 23 or the like is processed according to the control program. The HDD 24 stores a business application 31 and a spooler 32.

The CPU 21 executes the business application 31 and generates a desired ringing pattern based on the input from the input device 25. The ring pattern includes items such as frequency, ring time, mute time, volume, and number of rings. The user can generate a desired ringing pattern or ringing stop pattern by changing parameters for these items.

In addition, when receiving information (hereinafter referred to as coupon information) for issuing a coupon from a POS application or the like, the CPU 21 executes the business application 31 and generates print data based on the coupon information. Then, the business application 31 sends the print data generated together with the print request to the spooler 32. The spooler 32 generates a print job based on the print data and assigns a print job ID to the print job. This print job includes a JobStart command that indicates the head of the print job, a JobName command that describes the print job ID, and a JobPrint that instructs printing of print data.
It is formed from a print control command such as a t command, a JobEnd command indicating the end of the print job, and print data. Then, the spooler 32 notifies the business application 31 of the print job ID as a response to the print request, whereby the business application 31 acquires the print job ID. Further, the CPU 21 transmits a print job generated from the spooler 32 via the communication interface 26 to the printer 3 (print job transmission unit).
.

The business application 31 determines whether or not the print job ID is a predetermined print job ID (for example, a print job ID for the last coupon issued to one customer) (print job determination unit). When the print job ID is a predetermined print job ID, the business application 31 generates a ring control command by associating the ring pattern and the print job ID. Then, the CPU 21 transmits the ring control command to the printer 3 via the communication interface 26 using the API of the business application 31 (notification control command transmission means). By transmitting only the ringing control command related to the predetermined print job, it is possible to notify only the completion of the predetermined print job in the printer 3, which will be described later, that is, the fact that the predetermined coupon has been issued. For example, when issuing a plurality of coupons to one customer, by notifying only the completion of the print job that issues the last coupon, the operator can issue all coupons issued before the notification to one customer. It can be surely recognized that it is a thing, and forgetting to hand over the coupon can be prevented.

Note that the transmission of the print job and the transmission of the ring control command are performed asynchronously, the ring control command is transmitted using User Datagram Protocol (UDP), and the print job is T
It is transmitted using CP (Transmission Control Protocol). Since these data (print job, ringing control command) are transmitted by the packet communication method, for example, when the ringing control command is transmitted following the print job, a close process for recognizing the end of the print job data is performed. At the stage of completion, an open process for recognizing the start of data of the next ring control command is performed. In other words, due to the time required for these processes, there is a delay between the completion of the print job execution and the actual execution of the ring control command. On the other hand, in this embodiment, by performing asynchronous transmission, it is possible to transmit a ringing control command without being affected by the status of the print job, and packet processing such as the above-described close processing and open processing. Since there is no need to wait for the completion of the print job, it is possible to prevent a delay from the completion of execution of the print job to the start of execution of the ring control command.

The printer 3 includes a CPU 41, a flash ROM 42, a RAM 43, a communication interface 44, a print control unit 45, a paper transport mechanism 47, a print head 48 (printing means), and a buzzer 46.
(Notification means) and an LED lamp 16 are provided. Then, data in the RAM 43 is processed according to the control program stored in the flash ROM 42. RAM
43 is provided with a job history storage area 51 (job history storage means) in which a job history of a print job is recorded. In this job history storage area 51, a print job that has already been printed and a currently printing process are being performed. The print job ID corresponding to the print job is recorded. Further, the RAM 43 has a print job ID storage area 52 for recording a print job ID corresponding to a print job currently being printed, and a command storage area 53 (for recording a ringing control command).
Storage means) is provided.

The CPU 41 receives a ring control command from the host computer 2 via the communication interface 44 (notification control command receiving means). In this case, the CPU 41 determines whether or not the print job ID included in the ringing control command matches the print job ID of the currently executing print job recorded in the print job ID storage area 52. If the print job ID matches the print job ID of the print job currently being executed, the CPU 41 records the ring control command in the command storage area 53. On the other hand, if they do not match (including the case where no print job is currently being executed), the CPU 41 determines whether or not the print job ID included in this ringing control command is recorded in the job history storage area 51 ( (Second notification discriminating means) and controlling the ringing of the buzzer 46 based on the discrimination result. Specifically, when the print job ID is not recorded in the job history storage area 51, the CPU 41 temporarily records the ring control command in the command storage area 53. On the other hand, the print job ID is stored in the job history storage area 5.
1, the CPU 41 immediately sounds the buzzer 46 based on the sound pattern included in the sound control command. When receiving the ring control command, it is determined whether or not there is a print job ID identical to the print job ID of the ring control command. The print job ID that records only the print job ID that is currently started
By making a determination by referring to the storage area 52 first, it is possible to make a determination more quickly than when searching and determining the job history storage area 51 in which a plurality of print job IDs are recorded. That is, the process related to the sounding of the buzzer 46 can be quickly executed. Thus, for example, even when the ringing control command is delayed for some reason, it is possible to reliably notify the operator that the print job has been completed, that is, a coupon or the like (printed matter) has been issued.

On the other hand, the CPU 41 receives a print job from the host computer 2 via the communication interface 44 (print job receiving means). The CPU 41 executes processing based on the print control command of the received print job. Specifically, first, the CPU 41 executes JobSt.
Processing of the print job is started by analyzing the art command, and then JobName
Parse the command. This JobName command includes the print job ID of the print job.
Is set as a parameter, and the CPU 41 acquires the print job ID of the print job. Then, the CPU 41 sets the print job ID as the print job ID.
The status of printing is recorded in the storage area 52 and the job history storage area 51. Next, the CPU 41 analyzes the JobPrint command and starts printing the print data. In this case, the CPU 41 issues a print instruction based on the print data to the print control unit 45. Upon receiving the print instruction, the print control unit 45 drives the print head 48 to execute printing on the roll paper while transporting the roll paper via the paper transport mechanism 47 based on the print data, and discharges the paper. A coupon is issued from the exit 15. After the printing (operation) is completed, the CPU 41 analyzes (processes) the JobEnd command included in the print job (printing control command), and when the analysis of the command is completed, all the processing related to the print job is completed. Detect (
Print job completion detection means).

Using this detection result as a trigger, the CPU 41 determines whether or not a ringing control command including the same print job ID as the print job ID of the print job exists in the command storage area 53 (first notification determination unit). If there is a corresponding ring control command, the CPU 41 controls the buzzer 46 based on the ring pattern included in the ring control command to make a ring and update the job history storage area 51 to print the status of the print job. Complete. Further, after the buzzer 46 has finished ringing, the CPU 41 clears the ringing control command stored in the command storage area 53. On the other hand, if there is no corresponding ringing control command, the job history storage area 51 is updated, and the status of the print job is set to print completion.

Here, a procedure for generating a print job and a ringing control command will be described with reference to FIG. First, when receiving the coupon information, the host computer 2 generates print data based on the coupon information (S01). Next, the host computer 2 generates a print job based on the generated print data (S02) and assigns a print job ID to the print job (S03). Then, the host computer 2 transmits the print job to the printer 3 (S04, print job transmission means). On the other hand, the host computer 2 determines whether or not the print job ID is a predetermined print job ID (S05,
Print job discrimination means). When the print job ID is a predetermined print job ID (S06)
Yes), the host computer 2 generates a sound control command in which the print job ID and the sound pattern of the buzzer 46 are set (S07). And host computer 2
Transmits this ringing control command to the printer 3 asynchronously with the transmission of the above-described print job (S08, notification control command transmission means), and completes a series of processing (S09). On the other hand, if the print job ID is not a predetermined print job ID (S06; No), the host computer 2 completes the process without generating a ring control command (S09).

Next, an operation procedure when the printer 3 receives a print job will be described with reference to FIG. First, the printer 3 receives a print job transmitted from the host computer 2 (S11, print job receiving means). Then, the printer 3 starts print processing based on the print job (S12). At this time, the printer 3 acquires the print job ID included in the print job, and records (registers) the print job ID in the job history storage area 51 and the print job ID storage area 52 as the status during the printing process (S13). ). When the printer 3 detects that a series of print processing based on the print job is completed (S14, print job completion detection unit), the ring control command including the same print job ID as the print job ID of the print job. Is present in the command storage area 53 (S15, first notification determination means). If there is no target ring control command (S16; No), the printer 3 updates the status for the print job ID in the job history storage area 51 to the completion of the printing process (S19). On the other hand, if there is a target ring control command (S1
6; Yes), the printer 3 uses the buzzer 4 based on the ringing pattern of the ringing control command.
6 is sounded (S17). After the buzzer 46 has finished ringing, the printer 3 clears the ringing control command recorded in the command storage area 53 (S18). Then, the printer 3 updates the status for the print job ID in the job history storage area 51 to the completion of the printing process (S19).

Next, an operation procedure when the printer 3 receives a ringing control command will be described with reference to FIG. First, the printer 3 receives the ring control command transmitted from the host computer 2 (S21, notification control command receiving means). Then, the printer 3 receives the print job ID that is the same as the print job ID included in the received ring control command.
It is determined whether or not it is recorded in the D storage area 52 (S22). That is, it is determined whether or not the print job to which the print job ID included in the ringing control command is assigned is being printed. When the target print job ID exists in the print job ID storage area 52 (S23)
; Yes), the printer 3 records the ring control command in the command storage area 53 (S2).
4). On the other hand, when the target print job ID does not exist in the print job ID storage area 52 (S23; No), the printer 3 searches the job history storage area 51, and the target print job ID is the job history storage area. It is discriminate | determined whether it is recorded on 51 (S25, 2nd alerting | reporting discrimination means). If the target print job ID does not exist in the job history storage area 51 (S26; No), the printer 3 records the ring control command in the command storage area 53 (S24). On the other hand, when the target print job ID exists in the job history storage area 51 (S26; Yes), the printer 3 has the status of the print job ID recorded in the job history storage area 51 “print processing completed”. It is determined whether or not. If the status of the target print job ID is other than “print processing completed” (S27; No), the ring control command is recorded in the command storage area 53 (S24). On the other hand, the target print job I
When the status of D is “print processing completed” (S27; Yes), the printer 3 immediately sounds the buzzer 46 based on the sound pattern of the sound control command (S28).

As described above, according to the present embodiment, the print job and the ringing control command are asynchronously transmitted from the host computer 2 to the printer 3. The printer 3 that has received these executes print processing based on the print job. Then, using the detection that the print job is completed as a trigger, the printer 3 causes the buzzer 46 to sound based on the sound pattern included in the sound control command including the same print job ID as the print job ID of the print job. Since the buzzer 46 sounds, the operator can grasp the completion of the print job, so that, for example, it is possible to recognize that the issuing process (print job) of a printed matter such as a receipt or a coupon has been completed. For this reason, by educating the operator to take out the printed material after the buzzer 46 rings, it is attempted to take out the printed material before the printing process is completed (particularly before the paper is cut) and tear the printed material. Can improve. As a result, the paper jam of the printer 3 due to the tearing is prevented, and the operation rate of the printing service can be improved.

In the present embodiment, a ringing pattern is generated on the host computer 2 side, and the ringing pattern is transmitted to the printer 3 to realize the ringing of the buzzer 46. However, the present invention is not limited to this. A plurality of ringing patterns may be stored in advance, and only the information specifying the ringing pattern may be transmitted from the host computer 2 to the printer 3 to ring the buzzer 46. Thereby, transmission of the ringing pattern itself becomes unnecessary, and traffic related to transmission of the ringing pattern can be reduced. In this case, the storage means (notification pattern storage means) for recording the ringing pattern corresponds to the flash ROM 42 shown in FIG.

In this embodiment, when a predetermined print job is completed, the buzzer 46 is sounded to notify the completion, but this is not restrictive. You may make it alert | report the completion of.

In the present embodiment, the coupon is described as an example of the printed matter to be a target, but the present invention is not limited to this.

It is also possible to provide the functions of the host computer 2 and the printer 3 shown in the above example as programs. It is also possible to provide the program stored in a storage medium (not shown). Recording media include CD-ROM, flash ROM,
Memory cards (compact flash (registered trademark), smart media, memory stick, etc.), compact discs, magneto-optical discs, digital versatile discs, flexible discs, and the like can be used.

Further, regardless of the above-described embodiments, the apparatus configuration, processing steps, and the like of the printing system 1 can be appropriately changed without departing from the gist of the present invention.
