Abstract
A printing apparatus and a printing method perform the steps of computing the shift value of each ejection port in accordance with the thermally-expanded width of a print head, dividing the shift value by a nozzle pitch, using the ejection port which number is minimum among ejection ports having the same integer value of the above quotient as a boundary position, using the print data printed at the boundary position as the logical sum between data for two consecutive ejection ports, and printing each of print data values for ejection ports having the same quotient integer value as the boundary position as the print data for an ejection port number obtained by adding the quotient integer value to the ejection port number of its own.
