摘要： PROBLEM TO BE SOLVED: To solve the delaying of the starting timing of the warm-up of a printer already under a power-saving mode due to once spooling of printing data, the consequent longer first printing time and poor operational convenience, and further a second power-saving mode which develops due to the requirement of a longer forming time of the printing data. SOLUTION: Before the spooling of the printing data in a printing job, the warm-up treatment is started in a printer under a power-saving mode so as to produce starting data for bring under a printable state in order to spool a printing job other than the printing data so as to send the data in advance to the printer. Thus, the spooling of the printing data and the warm-up treatment of printing equipment are performed in parallel, resulting in shortening the first printing time. Further, a command for setting a time to monitor the migration of the starting printing job and the printing data to the power-saving mode is added so as to prevent an unavailing warm-up treatment from performing. Furthermore, when printing conditions demand, a command for returning the printer under a stand-by mode is added to the starting data or the printing data.
