Patent ID: 7407244

Claim:
A printing method using an inkjet head, comprising the steps of: a) causing a printing medium to move in a predetermined direction of movement relative to a head which ejects droplets of ink from a plurality of outlets toward said printing medium; b) generating an ejection timing signal each time said printing medium travels a predetermined distance relative to said head, concurrently with said step a); c) inputting a driving signal for an operation related to ejection of droplets from said plurality of outlets based on writing data, to said head each time said ejection timing signal is generated; and d) inputting at least one non-ejection driving signal, each of which is a driving signal indicating a non-ejecting operation, to said head between driving signals respectively associated with one ejection timing signal and a next ejection timing signal generated subsequently to said one ejection timing signal in a case where an ejection interval which is a time period between generation of said one ejection timing signal and generation of said next ejection timing signal in said step b) is equal to or longer than twice a basic time period of input of driving signal which is fixed for said head.
