Abstract:
1. A printing device, comprising: a data receiving unit configured to receive print job data; a buffer used to store the received print job data; a judgment unit configured to judge whether the print job data received by the data receiving unit can be stored in available space of the buffer; a deletion target extraction unit configured such that, in response to the judgment unit judging that the print job data received by the data receiving unit cannot be stored in the available space of the buffer, the deletion target extraction unit extracts print job data different from the received print job data as deletion target print job data which can be deleted from the buffer, from among one or more pieces of print job data stored in the buffer; a buffer controller that controls the buffer such that: a reread judging unit configured to judge whether the print job data can be reread from a sender of the print job data; wherein the deletion target extraction unit extracts the print job data as the deletion target print job data in the buffer having a print designation time which is later than that of the print job data received by the data receiving unit and which is judged that it can be reread from the sender thereof, from the one or more pieces of print job data in the buffer; and wherein the deletion target extraction unit does not extract, as the deletion target print job data, the print job data in the buffer which is judged that it cannot be reread from the sender thereof, even if the print job data has the print designation time which is later than that of the print job data received by the data receiving unit.
