ABSTRACT:
A print controlling apparatus includes a printing head with columns of printing elements. A buffer circuit includes data storage columns corresponding to the printing element columns on the printing head. The buffer circuit also includes data storage columns corresponding to a printing region between the printing element columns on the printing head. Printing data is transferred from the data storage columns in the buffer circuit corresponding to the printing element columns on the printing head. After the data is transferred from the data storage columns to the printing head, a shift controlling circuit shifts printing data in the data storage columns corresponding to the intermediate region to the data storage columns corresponding to the printing element columns on the printing head. By storing and shifting data from the data storage columns corresponding to the printing region between the printing element columns on the printing head, processing time during a print cycle is reduced.
