PURPOSE:To swiftly and easily render printing conditions most suitable by providing a heating control means which, corresponding to environmental condition, furnishes a recording unit control means with an electric signal within a range in which a flying droplet should not be formed and having a frequency larger than the one at the time of recording, and performs heating of liquid. CONSTITUTION:The title device is provided with the following components: (a) a liquid jet recording unit 100 which has a discharge energy generating means 102 which includes an electrothermal energy conversion element which, corresponding to an electric signal supplied, can heat liquid and form a flying droplet, and the droplet is discharged against the material P to perform recording; (b) a recording unit control means 110 which can set a frequency of an electric signal, and furnishes the discharge energy generating means 110 with an electric signal to form a flying droplet correspond ing to the input of a recording signal SA; (c) a heating control means 140 which has a frequency setting means 144 which sets a frequency for the recording unit control means 110, and corresponding to an environmental condition, furnishes the recording unit control means 110 with an electric signal whithin a range in which a flying droplet should not be formed and has a frequency larger than the one at the time of printing, and performs heating of liquid. |
