Estimating the term…
The present invention provides an ink jet printing apparatus and a method for controlling temperature for the ink jet printing apparatus wherein the temperature of a print head, which may lower during printing, is controlled before printing without using any sub-heater to allow a favorable ejection condition to be established without reducing the head temperature below a predetermined value. Thus, scan width information and dot count information are acquired before a carriage starts scanning to determine the heating temperature of the print head on the basis of the information.
An ink jet printing apparatus that prints on a print surface of a print medium using a print head provided with an ejection port forming surface where an ejection port to eject ink is formed, the ink jet printing apparatus, further comprising:
An ink jet printing method comprising:
