PROBLEM TO BE SOLVED: To automatically set a best output schedule for waiting output data, by controlling, changing the output schedule for output data of an output information of each output job information stored in a memory means when it is judged that a consumable material becomes short during printing. SOLUTION: A host computer 2000 is connected to a printer control unit 1001 via an interface to carry out a control process for communication with a laser printer main body 1000. In the printer control unit 1001, a CPU 1-1 integrally controls according to a control program stored in a program ROM of a ROM 1-2 an access to each device connected to a system device 1-4, and outputs an image signal as an output information to a printing part 1-9 connected thereto via a printing part interface 1-8. A remaining amount calculation part 1-10 obtains information on the amount of the remaining paper, the amount of the remaining toner, etc., detected by a consumable remaining amount detection sensor provided in the printing part 1-9. |
