2. Description of the Related Art Conventionally, a printing apparatus which operates by receiving a print job from a host computer is known. In this apparatus, a series of print data from a print start to an end of print data including print data and a control code, that is, a “print job” is stored in a main storage device such as a built-in RAM or a secondary storage device such as a hard disk. It is configured to be able to hold a plurality. Then, in general, the processing of the held plurality of print jobs is executed in the order in which they are received by the printing apparatus.

[0003] When a printing apparatus is used in a network environment, a plurality of printing jobs from a plurality of users are transmitted to one printing apparatus at an arbitrary timing. For example, if a user issues a print job A and immediately after that another user issues a print job B, the process of the print job A is executed first, and after the process is completed, the process of the print job B is executed Will be done.

In a conventional apparatus, when it is desired to cancel the execution of a print job for some reason or the like, the print job can be designated and interrupted, and the data of the print job can be discarded or invalidated. It is configured as follows.

[0005]

However, in the above-mentioned conventional printing apparatus, print jobs are processed in the order of reception, and subsequent print jobs are not processed until the processing of the preceding print job is completed. If the processing of a print job is stalled for some reason, there is a problem that the processing of a subsequent print job may be delayed for a long time.

For example, if the preceding print job requires recording on a certain paper size, but the corresponding recording paper is not mounted, it is necessary to perform paper mounting work such as paper replacement. In this case, the processing of the print job is interrupted until an appropriate sheet is mounted. Then, the user who issued the subsequent print job arrives at the printing apparatus to obtain a print result, but the output of the subsequent print job is in a processing wait state because a paper replacement request has been generated by the preceding print job. There are quite a few situations that occur. If the issuer of the preceding print job does not promptly mount the appropriate paper, the processing of the subsequent print job is significantly delayed, thereby deteriorating the efficiency of the printing operation.

[0007] Such a situation may occur, for example, when a print job requires double-sided printing but the optional duplex printing device is not installed, or when the print job requires output in a font that is not in the built-in font. Even if the font ROM or the like is not installed, the same occurs due to various reasons.

On the other hand, simply discarding or invalidating a print job whose processing has been interrupted each time requires re-issuing the print job, which is complicated.

(Hereinafter, referred to as “LBP body 100”) forms an image on recording paper in accordance with print information supplied from a host computer H or the like (not shown) connected to the outside. A plurality of host computers H can be connected, and a print job, which is a series of print data from the start to the end of printing of print data including print data and control codes, is sent from the host computer H at an arbitrary timing. 1
It is sent to 00.

The operation panel section 120 has switches for various operations, an LED display, and the like (not shown). The formatter control unit 110 controls the LBP body 10
0 and analyzes the character information and the like supplied from the host computer H to perform the printing process.

The print information developed by the formatter control unit 110 is converted into a video signal of a corresponding pattern and output to the laser driver 131. The laser driver 131 is a circuit for driving the semiconductor laser 141, and operates in accordance with the input video signal.
The on / off of the laser light 142 emitted from 1 is switched.

The laser beam 142 is swung right and left by the rotary polygon mirror 143 and is scanned and exposed on the electrostatic drum 144. As a result, an electrostatic latent image of a character pattern is formed on the electrostatic drum 144. This latent image is developed by a developing unit 145 disposed around the electrostatic drum 144 and then transferred to a recording sheet. A cut sheet is used as the recording paper. The cut sheet recording paper is stored in a paper cassette 146 mounted on the LBP main body 100, and is supplied with a paper feed roller 147 and transport rollers 148,

FIG. 2 is a block diagram showing a control configuration of the printing apparatus.

In the control configuration of the present apparatus, the CPU 2 (executability determining means, control means, user intention confirming means, executing means) is connected to the ROM 3, RAM 4, communication control section 5 (print job receiving means) via the CPU bus 2a, LCD / LED6
(Display means), operation panel 7, NV-RAM (Non Vola
tile RAM) 8 and a hard disk (HD) 9 are connected.

The CPU 2 is composed of a microcomputer or the like, and operates according to a program stored in the ROM 3.
The overall control of the apparatus is controlled via the PU bus 2a. RAM
Reference numeral 4 is used as a work area of the CPU 2. The communication control unit 5 controls communication with the host computer H. The LCD / LED 6 includes an LCD display and an LED lamp. The operation panel 7 is used for setting a printing environment and the like.

The NV-RAM 8 stores information such as a predetermined set time T (predetermined time) in the area 8a. The predetermined set time T is a time for determining whether to save the print job on the hard disk 9 in a print job process described later, and is set to an arbitrary value by the operation panel 7 or the print environment setting data. If these are not set, they are set to the default values stored in the ROM 3.

The hard disk 9 can store a plurality of print jobs received from the host computer H in the data area 9a.

FIG. 3 is a diagram showing a flowchart of the print job processing in this embodiment. This processing is CPU

First, a print job sent from the host computer H is read (step S101), and data analysis is performed (step S102). In this data analysis, the paper size requested by the print job, that is, the paper size defined in the print job is checked. Next, based on the result of the data analysis, it is determined whether or not a paper cassette of a paper size requested by the print job is mounted on the LBP main body 100 (step S103).

As a result of the determination, if the paper cassette of the paper size requested by the print job is mounted on the LBP main body 100, the print process is immediately executed for the print job (step S106), and the present process ends. .

On the other hand, if the paper cassette of the paper size requested by the print job is not mounted on the LBP main body 100, an operator call is issued (step S10).
4). In other words, for example, an operator call having a meaning of “the printing apparatus does not have the paper size required for the print job” is generated. As the operator call, a message such as “North A3” is displayed on the LCD display of the LCD / LED 6, or
Alternatively, a warning buzzer or the like may be sounded, or both of them may be performed.

Next, a timer, which is one of the functions of the CPU 2, is operated to set the elapsed time p after the occurrence of the operator call.
t is started (step S105), and the paper cassette of the paper size requested by the print job is
Is determined (step S106).

As a result of the determination, if the paper cassette having the paper size requested by the print job is mounted on the LBP main body 100, the process proceeds to step S109 to execute the printing process, while the paper size requested by the print job is still being processed. When the paper cassette of No. is not mounted on the LBP main body 100, the elapsed time pt after the occurrence of the operator call is N
It is determined whether or not a predetermined set time T stored in the V-RAM 8 has been reached (step S107).

If it is determined that the elapsed time pt has not reached the set time T, the flow returns to step S106. Therefore, the determinations in steps S106 and S107 are repeated until a paper cassette of the paper size required by the print job is mounted or until the elapsed time pt reaches the set time T.

On the other hand, if the elapsed time pt has reached the set time T, the print job to be processed is stored in the data area 9a of the hard disk 9 (step S1).
08), this process ends. As a result, execution of a print job that cannot be processed immediately can be suspended, and processing can be shifted to a later print job. When the print job is stored, the login name of the user who transmitted the print job is also stored. As a result, as will be described later, when the print job stored in the hard disk 9 is executed later, it is easy to search for and specify the print job.

FIG. 4 is a diagram showing an example of a display when a print job is stored on the hard disk. This display is made on the LCD display of the LCD / LED 6.

When the user goes to the printing apparatus to obtain his or her own output result, but there is no output result, this display indicates that his or her print job has been saved without being executed.

FIG. 5 is a state transition diagram showing the flow of operations when a print job stored in the hard disk 9 is confirmed and output processing is executed. This operation is performed by the operation panel 7.

The utility menu includes an item "HD Saved Data" along with various utilities such as a status print and a font list. Here, "HD storage data" is selected with left and right arrow keys (not shown) (step S503), "HD storage data" is displayed, and a down arrow key (decision button) not shown is pressed (step S504). ), And enters a print job selection mode.

In the print job selection mode, the user moves and displays his / her user name (login name) (for example, user name C) using the left and right arrow keys (step S505). When the arrow key (decision button) is pressed (step S506), the printing process of the print job is executed (execution unit).

According to the present embodiment, when the paper cassette of the paper size requested by the print job is not mounted in the LBP main body 100, the requested paper is not generated even after the set time T has elapsed after the operator call is generated. When the paper cassette of the size is not mounted, the print job is stored in the hard disk 9, so if there are a plurality of print jobs to be processed, the processing is interrupted for a long time to cope with the preceding print job processing. Can be avoided, and congestion in the processing of a subsequent print job can be suppressed. This allows
The efficiency of the printing operation can be improved. Further, since the print job stored in the hard disk 9 can be executed later, it is not necessary to issue the same print job again. In addition, since the stored print job is displayed in a menu format and the user selects a print job, the print job whose execution is suspended can be executed by a simple operation.

Further, by generating an operator call, it is possible to promptly prompt the user to take appropriate action. Even if the necessary paper cassette is not mounted, if it is mounted before the set time T elapses,
Since the printing process is executed, an appropriate time allowance for the processing of the preceding job processing is given, and the processing of the preceding printing job can be executed as long as the processing is appropriately performed.

(Second Embodiment) In a second embodiment of the present invention, when a paper cassette of a paper size requested by a print job is not mounted on the LBP main body 100,
The difference from the first embodiment is that the timing at which a print job is stored in the hard disk 9 is controlled depending on whether or not the user intends to immediately carry out the mounting operation. Other configurations are the same as those of the first embodiment. Is the same as

FIG. 6 is a diagram showing a flowchart of the print job processing in this embodiment. This processing is CPU
2 is performed.

First, in steps S201 to S204,
The same processing as steps S101 to S104 in FIG. 3 is executed. After the process in step S204, the user of the host computer H that has transmitted the print job is notified of the user's intention, that is, the fact that the paper cassette of the paper size requested by the print job is not mounted on the LBP main body 100. (Step S205). This notification includes a message confirming the user's intention, "Do you intend to prepare the paper cassette of the required size immediately for the printing device?" Or "Do you intend to prepare when the time becomes available later?" This is displayed on the host computer H.

FIG. 7 is a diagram showing an example of a display message for confirming the user's intention regarding paper preparation. As shown in the drawing, a message that a paper cassette of a required size is not mounted and a selection item of “prepare paper” or “prepare paper later” are displayed. The user
When one of them is input, the information is transmitted to the printing apparatus.

Next, it is determined whether or not the user has an intention to immediately prepare (predetermined processing) the paper cassette (step S206) (user intention confirmation means). As a result of the determination, if the user selects “prepare paper later”, it is determined that the user does not intend to immediately prepare the paper cassette, and the process proceeds to step S210, and the same as step S108 in FIG. The print job to be processed is stored in the data area 9a of the hard disk 9, and the process ends. When the print job is stored, the login name of the user who transmitted the print job is also stored.

On the other hand, when the user selects "prepare paper", the user operates the timer of the CPU 2 assuming that the user intends to immediately prepare the paper cassette.
The measurement of the elapsed time pt 'after the notification of the user's intention confirmation is started (step S207), and it is determined whether or not the paper cassette of the paper size requested by the print job is mounted on the LBP main body 100 (step S208).

As a result of the determination, if a paper cassette having the paper size required by the print job is mounted on the LBP main body 100, the process proceeds to step S211 to execute the printing process, while the paper size still required by the print job is maintained. When the paper cassette is not mounted on the LBP main body 100, the elapsed time pt 'after the notification of the user's intention is set to N
It is determined whether a predetermined set time T stored in the V-RAM 8 has been reached (step S209).

If it is determined that the elapsed time pt 'has not reached the set time T, the flow returns to step S208. Therefore, the determinations in steps S208 and S209 are repeated until a paper cassette of a paper size required by the print job is mounted or until the elapsed time pt 'reaches the set time T.

On the other hand, when the elapsed time pt 'has reached the set time T as a result of the determination in the step S209, the process proceeds to the step S210 and the hard disk 9 is stored in the hard disk 9.

According to the present embodiment, the user's intention is confirmed by the user's intention confirmation notice, and if the user intends to immediately prepare the paper cassette requested by the print job, the set time T after the user's intention confirmation notice is given. If the paper cassette of the requested paper size is not installed after
Since the print job is stored in the hard disk 9, not only the processing congestion of the subsequent print job can be prevented and the same effect as in the first embodiment can be achieved with respect to the omission of the trouble of reissuing the print job, but also If the user does not intend to immediately prepare the paper cassette requested by the print job, the print job is immediately stored in the hard disk 9. Therefore, when the preceding print job has no urgency, the processing is performed on the subsequent print job. The process can be shifted promptly to minimize processing congestion.

The user's intention confirmation notification is sent not from the printing apparatus but from the host computer H which has transmitted the print job.
Since it is displayed above, the intention of the issuer of the preceding print job can be quickly confirmed.

In each of the above embodiments, the case where the paper cassette of the paper size requested by the print job is not mounted on the LBP main body 100 is exemplified as the reason that the print job cannot be executed. However, the present invention can be widely applied to a case where even if the preceding print job cannot be executed, there is a possibility that a later print job can be executed. For example, a print job requires duplex printing, but a duplex printing option device for duplex printing is not installed and needs to be installed, or the print job requires printing in a specific font. However, the corresponding font information is not built-in, and a storage medium (extended font, etc.) such as a font ROM storing the corresponding font information is stored.
This can be similarly applied when it is necessary to attach a.

Note that the data is temporarily stored in the hard disk 9 and
The print job process shown in FIGS. 3 and 6 is applied between print jobs that are instructed to be executed later and between a print job that is instructed to be executed later and a print job newly received from the host computer H. If execution is not possible, the subsequent print job may be processed first.

In each of the above embodiments, a similar effect can be obtained by reading out a storage medium storing a control program represented by software for achieving the present invention into a printing apparatus or a system. it can.

FIG. 8 is a diagram showing an example of a memory map of a storage medium used in the printing apparatus. The directory information indicates the storage location where the code of each process is stored.
As shown in the figure, for example, a ROM (not shown) as a storage medium used in a printing apparatus is used in a printing apparatus control method for controlling a printing apparatus capable of executing a plurality of print jobs in the order of reception. A program is stored, and a code of a print job receiving step, a code of an execution determination step,
The code of each step of the code of the control step is stored. The code of each step has the following functions. That is,
The print job receiving step code receives a print job from a host computer. The code of the execution determination step determines whether the printing process according to the print job received by the code of the print job reception step is executable. The code of the control step stores the print job without executing the print job when it is determined by the code of the execution determination step that the print processing according to the received print job is not executable, Control is performed so that the processing is shifted to the subsequent print job received by the code of the print job receiving step after the print job.

The storage medium in these cases is as follows.
In addition to the ROM, a floppy disk, a hard disk, an optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, and the like can be used.

Further, after the program code read from the storage medium is written into a memory provided in a function expansion board inserted into the computer or a function expansion unit connected to the computer, based on the instruction of the program code, The case where the CPU of the function expansion board or the function expansion unit performs part or all of the actual processing, and the function of the above-described embodiment is realized by the processing.
