Description

TECHNICAL FIELD The present disclosure relates to the technical field of image forming and, more particularly, to a control method for forming an image, an image forming apparatus, a device, and a storage medium. BACKGROUND In existing technologies, an image-forming device may be shared by multiple users, and may receive multiple consecutive image-forming jobs sent by one or more users to perform an image-forming operation. Generally, during an image-forming process, the image-forming device will continuously output multiple sheets of paper to complete image-forming. Therefore, paper for multiple image-forming jobs from one user, or paper for image-forming jobs from multiple users will be stored in a paper discharge tray in a mixed manner. Therefore, when the user subsequently separates the paper for different image-forming jobs, the paper can only be retrieved and separated by human eyes, which is cumbersome and inefficient. Document US 2011/242577 discloses a method executed by an image forming apparatus for producing a print job, which includes the steps of receiving data representing a document to be printed; receiving job information about the print job, the job information including an instruction to print multiple copies of the document; printing the multiple copies of the document; and ejecting one sheet of each of the multiple copies of the document at an ejection speed, that is either greater than or less than an ejection speed of the other sheets of the multiple copies of the document.
