Abstract

A printing device executes printing every time when a print execution instruction is issued. The printing device include a data receiving unit configured to receive print data from an external device, a print target data storing unit configured to store print target data to be referred to when the printing operation is executed from among the data received by the data receiving unit, a switching judgment unit configured to judge whether the print target data currently stored in the print target data storage unit should be overwritten with newly received print data, a switching unit configured to switch the print target data stored in the print target data storing unit to the received data when the switching judgment unit determines that the print target data is to be switched, and a holding unit configured to hold the received data until the print target data is determined to be switched.
