Description

  The present invention relates to a printing system that transmits print data from an information processing apparatus to a printing apparatus via a network such as a communication line and causes the printing apparatus to print the print data.

Conventionally, in a printing apparatus (printer) that prints print data received via a network, when a print execution command is not received for a predetermined time, the operation state is changed from a standby state to a sleep state with low power consumption. In some cases, a sleep function that shifts to and from is mounted. According to such a sleep function, it is possible to reduce power consumption during standby and to save power in a printer (for example, Patent Document 1). See).
JP 10-175353 A

  However, conventional printers are configured to start print processing after performing return processing for returning the operation state from the sleep state to the standby state when a print execution command is received in the sleep state. The waiting time from when the user issues a print execution command to the printer until obtaining the printed matter is the return processing time in addition to the print processing time.

  In order to solve such a problem, for example, in Patent Document 1 described above, the information processing apparatus performs a return process via a printer driver in response to a user opening a print dialog for setting a print process. A technique for transmitting an instructed sleep release command to a printer is disclosed, and according to such a technique, the waiting time of a user is shortened compared to a case where a return process is performed after an instruction to execute a print process is issued. can do.

  However, in this technique, the wake-up command is transmitted only when the user opens the print dialog, in other words, only after indicating the intention to print. The time requires most of the return processing time in addition to the print processing time, and cannot be significantly reduced.

  SUMMARY An advantage of some aspects of the invention is that it provides a printing system capable of reducing a user's waiting time to a printing processing time.

  In order to solve the above problems, a printing system which connects a plurality of information processing apparatuses and a plurality of printing apparatuses via a network according to the present invention, and transmits print data from any information processing apparatus to any printing apparatus for printing. The information processing apparatus generates a sleep release condition table that associates a sleep release event that shifts the operation state of the printing apparatus from the sleep state to the standby state for each combination of an application that creates print data and a printing apparatus that prints print data. The sleep release condition table storage unit that stores information on the application started on the information processing apparatus, identifies the occurrence of an operation event of the information processing apparatus, and the sleep event that stores the operation event in the sleep release condition table The operation event is a wake event. A task management unit that lists all the printing apparatuses corresponding to the activated application, and a sleep start / cancellation instruction that transmits a sleep cancellation command to the printing apparatus corresponding to the application activated by the instruction of the task management unit A printer sleep determination unit that determines the operation state of the printer, and a printer sleep determination unit that receives the sleep release command from the information processing device, acquires the operation state from the printer sleep determination unit, and is in a standby state only in the sleep state. And an operation state instructing unit to be shifted to.

  Further, when the task management unit identifies the sleep release event, the task management unit acquires the operation state from the printing apparatus and transmits the sleep release command from the sleep start / release instruction unit to the printing apparatus only in the standby state. To do.

  Furthermore, after the sleep start / release instruction unit transmits a sleep release command to the printing apparatus, the task management unit does not send a print command even if the sleep standby time stored in the sleep release condition table has elapsed. When a sleep start command is transmitted from the release instruction unit to the printing apparatus, and the operation state instruction unit of the printing apparatus receives the sleep start command from the information processing apparatus, obtains the operation state from the printer sleep determination unit and is in a standby state. Only the sleep state is shifted.

  According to the printing system of the present invention, an operation event of the information processing apparatus is identified, and when the operation event is a sleep release event set in advance by the user, a sleep release command is transmitted to the printing apparatus, and the printing apparatus performs printing. Even if the command is not received, if the operation state is the sleep state, the standby state is entered, so that the waiting time of the user can be shortened to the print processing time.

  The application-printer driver related information storage unit 14 stores a sleep release condition table.

  The application-printer driver related information editing unit 15 controls the display screen for customizing the sleep release condition table. The details of the sleep release condition table will be described later.

[Printer configuration]
The printer 4 is constituted by a general printing apparatus such as a laser beam printer, an ink jet printer, a stencil printing machine, etc., and as shown in FIG. 2, components such as a CPU, a memory, a printing mechanism, and an I / F (interface) are included. Have. The printer 4 has a function of receiving a sleep start command and a sleep release command from the information processing apparatus 3 via the I / F and shifting the operation state from the standby state to the sleep state and from the sleep state to the standby state. The CPU executes the computer program stored in the memory, thereby realizing the functions of the operation state instruction unit 42, the printer sleep determination unit 43, the control mechanism 46, and the like shown in FIG. The printing mechanism 45 performs printing under the control of the control mechanism 46.

  The operation state instruction unit 42 controls the control mechanism 46 according to the sleep start command and the sleep release command received from the sleep start / release instruction unit 13 via the I / F 41, thereby changing the operation state of the printer 4 to the sleep state. And control during standby.

  In addition, the operation state instruction unit 42 acquires the operation state of the printer 4 from the printer sleep determination unit 43 in accordance with the sleep ON / OFF investigation command received from the task management unit 12 and transmits it to the task management unit 12.

  Furthermore, the printer sleep determination unit 43 acquires information indicating the operation state of the printer 4 from the control mechanism 46, and determines whether the operation state is a sleep state, a standby state, or a print state.

  The control mechanism 46 controls the printing mechanism 45 according to the print command received via the I / F 41 to execute the printing process.

  Note that the sleep recovery time of the printers 4a, 4b, 4c, and 4d in this embodiment (the time from when the sleep release command is received until the printer returns to the standby state in the sleep state) is set as shown in FIG. It shall be.

  In the printing system 1 having such a configuration, when the information processing device 3 identifies the sleep release event set in the sleep release condition table, the information processing device 3 transmits a sleep release command to the printer 4 in advance of the user's print instruction. Since the operation state is shifted to the standby state, the waiting time until the user obtains a printed matter can be shortened to the print processing time.

  Hereinafter, a detailed description will be given with reference to the flowcharts shown in FIGS. 5 and 8, 9, and 10.

[Table setting process]
First, the procedure for performing the table setting process of the sleep release condition table will be described with reference to the flowchart shown in FIG.

  The flowchart shown in FIG. 5 is started in response to the activation of the information processing apparatus 3, and the table setting process proceeds to step S01.

  In the process of step S01, the user installs the sleep cancel utility 11 in the information processing apparatus 3.

  In the process of step S02, the user stores the sleep release condition table shown in FIG. 6 in the application-printer driver related information storage unit 14.

  Here, it is assumed that the sleep release utility 11 is stored in a server (not shown) connected via the network 2 or a storage medium readable by the information processing apparatus 3. Further, the sleep release condition table may be information in which default values are stored in advance in the application-printer driver related information storage unit 14, or the user may store information in the application-printer driver related information storage unit 14 in the same manner as the sleep release utility 11. You may remember.

  In the sleep release condition table, the sleep release of the information processing apparatus 3 for shifting the operation state of the printer 4 from the sleep state to the standby state for each combination of the printer 4 used for the printing process and the application 21 that prints the print data. In the example shown in FIG. 6, “application 21” that creates print data for each printer 4, “presence / absence of sleep ON / OFF investigation command support function” of printer 4, “sleep release event”, and “sleep standby” “Time” and the like are set as default values. However, the presence / absence of the sleep ON / OFF investigation command support function of the printer 4 is a function of the printer 4 and cannot be customized (setting change).

  The sleep ON / OFF investigation command is a command for the task management unit 12 to acquire the operation state (sleep state, standby state, print state) of the printer 4 from the printer 4.

  The sleep release event is an operation event of the information processing apparatus 3 that transmits a sleep release command to the printer 4 when the task management unit 12 identifies the occurrence of the operation event from the operation events of the information processing apparatus 3. is there. For example, in this embodiment, the user can select from among the operation events of the information processing apparatus 3 shown in FIG. 7 for each combination of the printer 4 and the application 21 as a sleep release event for shifting the operation state of the printer 4 from the sleep state to the standby state. One or more can be set.

  Furthermore, the task management unit 12 transmits a sleep start command when a print command is not transmitted (for example, event A shown in FIG. 7 is identified) after transmitting a sleep release command. The time from the sleep cancel command transmission to the sleep start command transmission at this time is defined as a sleep waiting time. That is, it is the time for the printer 4 to continue the standby state.

  In the process of step S03, the application-printer driver related information editing unit 15 displays a screen for inquiring whether the stored sleep release condition table needs to be customized on the display screen, and the user uses the keyboard 29 or the mouse 30 to indicate whether the customization is necessary. input. The application-printer driver related information editing unit 15 determines whether or not the sleep release condition table input by the user needs to be customized. As a result of the determination, if the sleep release condition table needs to be customized, the application-printer driver related information editing unit 15 advances the process to step S04, and ends the process if customization is not necessary.

  In the process of step S04, the application-printer driver related information editing unit 15 displays a sleep cancel condition table customization screen on the display device, and the user operates the keyboard 29 or the mouse 30 to customize the sleep cancel condition table. When the customization is completed, the application-printer driver related information editing unit 15 stores the customized sleep release condition table in the application-printer driver related information storage unit 14 and ends the process.
