Patent ID: 8675235

Claim:
A printing apparatus which performs printing on a recording paper sheet, comprising: a storage section which stores a plurality of printing jobs to be printed on the recording paper sheet; a transport section which transports the recording paper sheet; a printing section which performs the printing on the recording paper sheet transported by the transport section based on one of the printing jobs stored in the storage section; an occurrence rate judging section which calculates an occurrence rate of a jam of the recording paper sheet in the transport section during the printing based on each of the printing jobs stored in the storage section, and which compares a first occurrence rate which is the occurrence rate during the printing based on a first printing job stored first in the storage section with a second occurrence rate which is the occurrence rate during the printing based on a second printing job stored second in the storage section; and a control section which controls the printing section so that the printing based on the second printing job is performed before the printing based on the first printing job is performed, in a case that the occurrence rate judging section judges that the second occurrence rate is smaller than the first occurrence rate, wherein in a case that the occurrence rate judging section judges that the first occurrence rate during the printing based on the first printing job is smaller than a first value, the occurrence rate judging section compares the first occurrence rate with the second occurrence rate.
