Image forming apparatus performing hold printing, control method therefor, and storage medium storing control program therefor

An image forming apparatus comprising:

• a setting unit configured to set one of a valid state and an invalid state about a forcible hold printing function that holds print job data when the print job data is received and prints using the print job data held in response to a user's print instruction;
• a storage unit configured to store the print job data;
• and
• a management unit configured to manage an attribute of the print job data stored and configured to change an attribute of time-setting print job data that will start printing at set-up designated time to an attribute corresponding to hold-print job data that starts printing in response to a user's print instruction when the time-setting print job data is stored in the storage unit and when the forcible hold printing function is switched from the invalid state to the valid state before printing using the time-setting print job data concerned.

A control method for an image processing apparatus, the control method comprising:

• a setting step of setting one of a valid state and an invalid state about a forcible hold printing function that holds print job data when the print job data is received and prints using the print job data held in response to a user's print instruction;
• a storing step of storing the print job data;
• and
• a deletion step of deleting time-setting print job data that will start printing at set-up designated time when the time-setting print job data is stored in the storage unit and when the forcible hold printing function is switched from the invalid state to the valid state before printing using the time-setting print job data concerned.

A control method for an image processing apparatus, the control method comprising:

• a setting step of setting one of a valid state and an invalid state about a forcible hold printing function that holds print job data when the print job data is received and prints using the print job data held in response to a user's print instruction;
• a storing step of storing the print job data;
• and
• a management step of managing an attribute of the print job data stored and of changing an attribute of time-setting print job data that will start printing at set-up designated time to an attribute corresponding to hold-print job data that starts printing in response to a user's print instruction when the time-setting print job data is stored in the storage unit and when the forcible hold printing function is switched from the invalid state to the valid state before printing using the time-setting print job data concerned.

A non-transitory computer-readable storage medium storing a control program causing a computer to execute a control method for an image forming apparatus, the control method comprising:

• a setting step of setting one of a valid state and an invalid state about a forcible hold printing function that holds print job data when the print job data is received and prints using the print job data held in response to a user's print instruction;
• a storing step of storing the print job data;
• and
• a deletion step of deleting time-setting print job data that will start printing at set-up designated time when the time-setting print job data is stored in the storage unit and when the forcible hold printing function is switched from the invalid state to the valid state before printing using the time-setting print job data concerned.
