Image forming apparatus with user authentication

An image forming method, comprising:

• spooling a normal print job in a first spooler,
• sequentially executing normal print jobs spooled in the first spooler,
• authenticating a user,
• executing a private print job spooled in a second spooler in response to inputting execution instruction of private print at an operation panel of an image forming apparatus,
• making effective a change key which changes the normal print job in an execution waiting state of the authenticated user to a private print job of the authenticated user, if the normal print job in the execution waiting state of the authenticated user is selected,
• moving the selected normal print job spooled in the first spooler into the second spooler as a private print job of the authenticated user in response to an input to the change key, and
• setting a password to execute the private print job in the private print job changed from the normal print job.

An image forming method comprising:

• authenticating a user,
• spooling a normal print job received from external equipment in a first spooler,
• making effective a change key which changes the normal print job in an execution waiting state of the authenticated user to a private print job of the authenticated user, if the normal print job in the execution waiting state of the authenticated user is selected,
• moving the selected normal print job spooled in the first spooler into a second spooler as a private print job of the authenticated user in response to an input to the change key, and setting a password to execute the private print job in the private print job changed from the normal print job.
