<p><P>PROBLEM TO BE SOLVED: To provide a printer which can prevent an event that cancel processing not intended by a user is carried out. <P>SOLUTION: A print command receiving time 38e which is a time when a print command is received at a reception processing part 18 is associated with print data 38g in job information data 38. When the job information data 38 is received at a print processing part 26, a new combination 40 in which a print data receiving time 38f, its receiving time is associated with the print data 38g is generated. The print processing part 26 invalidates printing by a printing part 30 of the print data associated with the print command receiving time earlier than an input time of the cancel command when a cancel command of canceling all of jobs is input, and invalidates printing by the printing part 30 of the print data associated with the print data reception time earlier than an input time of the cancel command when a cancel command of canceling a job being printed is input. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
