a determination unit configured to determine whether a second job which is a job subsequent to the first job is being executed in a case that the detection unit detects that the jam occurs in the sheet processing apparatus; and

a bundle determining unit configured to determine whether or not the first job and second job are bundled;

wherein, in a case (1) that the determination unit determines that the second job is being executed, and (2) the bundle determining unit determines the first or second job are bundled, the control unit controls a job execution order to execute the recovery job after executing the second job.

2. The print system according to claim 1 , further comprising:

a storage unit configured to store print data related to the first job,

wherein the control unit executes the recovery job based on the print data stored by the storage unit.

3. The print system according to claim 1 ,

wherein the control unit stops execution of the second job in a case that the detection unit detects that a jam occurs in the sheet processing apparatus, and

the control unit restarts the execution of the second job in a case that the jam is removed.

4. A print system including a print apparatus configured to execute print processing and a sheet processing apparatus configured to execute sheet processing of a sheet to which the print processing is executed, the print system comprising:

a detection unit configured to detect that a jam occurs in the sheet processing apparatus during execution of the sheet processing based on a first job;

a control unit configured to execute a recovery job corresponding to the first job in a case that the detection unit detects that the jam occurs in the sheet processing apparatus;

a determination unit configured to determine whether a second job which is a job subsequent to the first job is being executed in a case that the detection unit detects that the jam occurs in the sheet processing apparatus; and

a bundle determining unit configured to determine whether or not the first job and second job are bundled;

wherein, in a case (1) that the determination unit determines that the second job is being executed, and (2) the bundle determining unit determines the first or second job are bundled, the control unit stops the second job from being executed and executes the recovery job.

5. The print system according to claim 4 ,

wherein the control unit controls a job execution order to execute a job for printing remaining pages of the stopped second job after executing the recovery job.

6. The print system according to claim 4 , further comprising:

a storage unit configured to store print data related to the first job,

wherein the control unit executes the recovery job based on the print data stored by the storage unit.

7. The print system according to claim 4 ,

wherein the control unit stops execution of the second job in a case that the detection unit detects that a jam occurs in the sheet processing apparatus, and

the control unit executes the recovery job in a case that the jam is removed.

8. A print system including a print apparatus configured to execute print processing and a sheet processing apparatus configured to execute sheet processing of a sheet to which the print processing is executed, the print system comprising:

a detection unit configured to detect that a jam occurs in the sheet processing apparatus during execution of the sheet processing based on a first job;

a control unit configured to execute a recovery job corresponding to the first job in a case that the detection unit detects that the jam occurs in the sheet processing apparatus; and

a determination unit configured to determine whether a second job which is a job subsequent to the first job is being executed in a case that the detection unit detects that the jam occurs in the sheet processing apparatus; and

a setting unit configured to determine whether the recovery job is executed prior to the second job based on a user instruction,

wherein the control unit stops the second job being executed and executes the recovery job in a case that the determination unit determines that the second job is being executed and the setting unit determines that the recovery job is executed prior to the second job, and

the control unit controls a job execution order to execute the recovery job after executing the second job in a case that the determination unit determines that the second job is being executed and the setting unit determines that the recovery job is not executed prior to the second job.

9. The print system according to claim 8 , further comprising:

a display unit configured to display a selection screen for allowing a user to select whether to execute the recovery job prior to the second job,

wherein the setting unit determines whether the recovery job is executed prior to the second job based on a user instruction input via the selection screen.

10. The print system according to claim 9 ,

wherein the display unit displays the selection screen in a case that the detection unit detects that a jam occurs in the sheet processing apparatus.

11. The print system according to claim 8 , further comprising:

a storage unit configured to store print data related to the first job,

wherein the control unit executes the recovery job based on the print data stored by the storage unit.

12. A method for controlling a print system including a print apparatus configured to execute print processing and a sheet processing apparatus configured to execute sheet processing of a sheet to which the print processing is executed, the method comprising:

detecting that a jam occurs in the sheet processing apparatus during execution of the sheet processing based on a first job;

executing a recovery job corresponding to the first job in a case that an occurrence of the jam is detected in the sheet processing apparatus;

determining whether a second job which is a job subsequent to the first job is being executed in a case that an occurrence of the jam is detected in the sheet processing apparatus;

determining whether or not the first job and second job are bundled; and

controlling a job execution order to execute the recovery job after executing the second job in a case (1) that the second job is determined as being executed, and (2) the first or second job are bundled.

13. A non-transitory storage medium storing a program for causing a computer to execute a method according to claim 12 .

14. A method for controlling a print system including a print apparatus configured to execute print processing and a sheet processing apparatus configured to execute sheet processing of a sheet to which the print processing is executed, the method comprising:
