PROBLEM TO BE SOLVED: To obtain a printer system which shortens the queuing time of a print job having a short print time to efficiently perform the print processing. SOLUTION: In a printer system 10, a printer controller 12 prescans print jobs 15 when spooling plural print jobs 15 outputted from a higher device 26 to a spool 14 and estimates the print time on the basis of information on the numbers of print pages, data sizes, print attributes, etc., included in print jobs 15. In accordance with these estimated print time, print jobs 15 are divided into a class of jobs which have short print time and are enabled for interruption and a class of jobs which have long print time and are interruptible. When a prescribed time has passed after the start of print of a print job in the latter class, the remaining print time is calculated; and if there is a print hob 15 in the former class which has the print time longer than this remaining print time, this print job is executed by interruption.
