Abstract

A printing system includes printing apparatuses connected to a network. A control apparatus of the printing system may send a print job to each printing apparatus and instruct each printing apparatus to execute the print job. When a first printing apparatus is instructed to execute the print job, the control apparatus makes a substitute printing reservation. The substitute printing reservation is for a second printing apparatus to execute the print job instead of the first printing apparatus. The second printing apparatus is set to a waiting state in which the second printing apparatus waits to execute the print job instead of the first printing apparatus.

Claims

1. A printing system comprising:

a plurality of printing apparatuses connected to a network; and

at least one control apparatus, wherein the control apparatus sends a print job to at least one printing apparatus of the plurality of printing apparatuses and instructs the at least one printing apparatus to execute the print job,

wherein when a first printing apparatus from among the plurality of printing apparatuses is instructed to execute the print job, the control apparatus makes a substitute printing reservation for at least one second printing apparatus, wherein the substitute printing reservation allows the at least one second printing apparatus to execute the print job instead of the first printing apparatus,

wherein the at least one second printing apparatus for which the substitute printing reservation has been made is set to a waiting state for waiting to execute the print job instead of the first printing apparatus,

wherein the at least one second printing apparatus for which the substitute printing reservation has been made is held in the waiting state for waiting to execute the print job instead of the first printing apparatus until the substitute printing reservation is canceled by the control apparatus,

wherein when the at least one second printing apparatus for which the substitute printing reservation has been made enters a state in which a printing operation is disabled before the substitute printing reservation is canceled by the control apparatus, the at least one second printing apparatus requests the control apparatus to cancel the substitute printing reservation, and

wherein in response to a request for cancellation of the substitute printing reservation, the control apparatus cancels the substitute printing reservation for the at least one second printing apparatus that requested the cancellation of the substitute printing reservation and makes a substitute printing reservation for another printing apparatus.

2. The printing system according to claim 1,

wherein when the substitute printing reservation is made for the at least one second printing apparatus, the control apparatus sends control information of the print job to the at least one second printing apparatus.

3. The printing system according to claim 1,

wherein when the first printing apparatus completes the print job, the control apparatus cancels the substitute printing reservation made for the at least one second printing apparatus.

4. The printing system according to claim 1,

wherein when the at least one second printing apparatus executes the print job instead of the first printing apparatus, the control apparatus cancels substitute printing reservations made for any other printing apparatuses.

5. The printing system according to claim 1,

wherein when the first printing apparatus does not complete the print job, the control apparatus sends the print job to the at least one second printing apparatus for which the substitute printing reservation has been made and instructs the at least one second printing apparatus to execute the print job.

6. The printing system according to claim 1,

wherein if no printing apparatus is substituted for the first printing apparatus when the print job is started by one of the first printing apparatus and the at least one second printing apparatus for which the substitute printing reservation has been made, the control apparatus switches an operation mode of one of the first printing apparatus and the at least one second printing apparatus into a stability preference mode where stability is preferred.

7. The printing system according to claim 6,

wherein the stability preference mode is a mode in which a transporting speed of a sheet is slowed down.

8. The printing system according to claim 1,

wherein the at least one second printing apparatus for which the substitute printing reservation has been made enters a low power consumption state if the substitute printing reservation is canceled by the control apparatus.

9. The printing system according to claim 1,

wherein the substitute printing reservation includes setting information for controlling acceptance of a print job, and

wherein the at least one second printing apparatus, while in the waiting state for waiting to execute the print job instead of the first printing apparatus, performs acceptance of a print job from in accordance with the setting information included in the substitute printing reservation.

10. The printing system according to claim 1,

wherein the substitute printing reservation includes one of (i) setting information for inhibiting acceptance of a print job from the at least one control apparatus, (ii) setting information for permitting acceptance of only a print job in which a consumable supply specified in the substitute printing reservation is not used, and (iii) setting information for permitting acceptance of a print job from a control apparatus.

11. A printing apparatus, connected via a network to at least one control apparatus, executing a print job in accordance with an instruction from the at least one control apparatus for execution of the print job, the printing apparatus comprising:

an accepting unit configured to accept a substitute printing reservation made by the at least one control apparatus, the substitute printing reservation allowing the printing apparatus to execute a print job;

an apparatus state setting unit configured to, when the substitute printing reservation has been accepted, set the printing apparatus to a waiting state for waiting to execute the print job; and

a requesting unit configured to request cancellation of the substitute printing reservation when the printing apparatus enters a state in which a printing operation is disabled before the at least one control apparatus cancels the substitute printing reservation.

12. The printing apparatus according to claim 11,

wherein the apparatus state setting unit sets the printing apparatus to a low power consumption state if the substitute printing reservation is canceled by the at least one control apparatus.

13. The printing apparatus according to claim 11,

wherein the accepting unit accepts a print job in accordance with setting information included in the substitute printing reservation while in the waiting state.
