Claims (4)

A first data transfer path for temporarily storing the print data received from the host computer in the reception buffer memory and then transferring the print data to the print mechanism unit;
A second data transfer path for directly transferring to the printing mechanism without passing through the reception buffer memory;
A data transfer status determining unit for determining a data transfer status to the printing mechanism unit; and a print data transfer path to the printing mechanism unit based on a determination result of the data transfer status determining unit. A data transfer apparatus in a printing apparatus, comprising data transfer path switching means for switching to a transfer path. The data transfer path switching unit selects the second data transfer path when there is no stagnation in the transfer of print data to the printing mechanism unit as a result of the determination by the data transfer status determining unit, and the printing to the printing mechanism unit is performed. A data transfer apparatus in a printing apparatus, wherein the data transfer apparatus is configured to select the first data transfer path when data transfer is delayed. When the print data received from the host computer is transferred to the print mechanism within the printing apparatus, the received print data is temporarily stored in the reception buffer memory and then transferred to the print mechanism. A data transfer method that selectively employs the first data transfer method and the second data transfer method of transferring directly to the printing mechanism without going through the reception buffer memory,
When there is no stagnation in the transfer of the print data to the printing mechanism unit, the second data transfer method is adopted, and when there is a stagnation in the transfer of the print data to the printing mechanism unit, the first data transfer method is adopted. A data transfer method in a printing apparatus. A first data transfer path for transferring print data received from the host computer to the printing mechanism after passing through the receiving buffer memory, and directly transferring to the printing mechanism without passing through the receiving buffer memory A program for controlling a printing apparatus comprising a second data transfer path,
Controls the data transfer path switching unit to switch the print data transfer path to the printing mechanism unit to the first or second data transfer path based on the determination result of the data transfer status determination unit to the printing mechanism unit. A recording medium that stores the content program.
