Printing apparatus and printing method

A printing apparatus performing printing on a printing medium by controlling the driving of a printing head according to received data, said apparatus comprising:

• distinction means for distinguishing information content per unit area of the received data;
• mode selection means for selecting a printing mode according to slow printing velocity when said information content per unit area is large and selecting a printing mode according to fast printing velocity when said information content per unit area is small;
• and
• control means for setting said printing head at printing velocity according to said selected printing mode.

A printing method performing printing on a printing medium by controlling the driving of a printing head according to received data, said method comprising the steps of:

• distinguishing data compression rate of the received data;
• selecting a printing mode according to slow printing velocity when said data compression rate is low and controlling the driving of said printing head at printing velocity according to said selected printing mode to perform printing on said printing medium;
• and
• selecting a printing mode according to fast printing velocity when said data compression rate is high and controlling the driving of said printing head at printing velocity according to said selected printing mode to perform printing on said printing medium.
