Patent ID: 8472049

Claim:
An image forming system comprising a computing device configured to output a first print job and a second print job to an image forming apparatus, said image forming system comprising: a printing unit a processor; and memory storing computer-executable instructions that, when executed by the processor, cause the image forming system to: register the first print job as a locked job when a print request includes an unlocking condition and as a normal job when a print request does not include an unlocking condition; register the second print job, after registering the first print job, as a locked job when a print request includes an unlocking condition and as a normal job when a print request does not include an unlocking condition; determine whether the first print job is registered as the locked job or the normal job; determine whether the unlocking condition is fulfilled if the first print job is registered as the locked job; control the printing unit to conduct print processing of the first print job if the first print job is registered as the locked job and the unlocking condition is fulfilled or if the first print job is registered as the normal job; determine whether the second print job is registered as the locked job or the normal job; set the second print job into a prohibited state in which print processing is prohibited until the first print job is printed in response to determining that the second print job is registered as the normal job and the first print job is registered as the locked job but the unlocking condition is not fulfilled; judge whether the unlocking condition of the first print job is fulfilled within a reference time after registration of the first print job in response to determining that the first print job is registered as the locked job; and unlock the prohibited state of the second print job without deleting the first print job in response to judging that the unlocking condition of the first print job is not fulfilled within the reference time.
