Claim:
A printing system including a host device which creates print data in a page unit that comprises a plurality of pages or a single page and a printing device which prints out the print data transmitted from the host device, said printing device further including memory means for storing pages of the print data at least partially, wherein, when the print data exceed a memory capacity of the memory means, the print data are printed out and comprise first print data, which correspond to print data within the memory capacity of the memory means, and second print data, which correspond to print data exceeding the memory capacity of the memory means and which are transmitted from the host device; and re-transmission requesting means which requests the host device to re-transmit the second print data to the printing device when the print data are to be printed out in multiple copies, wherein printing of the print data of second and subsequent copies is carried out and comprises the first print data and the second print data, which are re-transmitted from the host device in response to the request of the re-transmission requesting means; and wherein the memory means stores a tailing side of the print data as the first print data and stores transmitted data from the host device from a leading side, and when stored data reaches the memory capacity, the memory means overwrites the stored data from the leading side so as to store the transmitted data.
