Abstract
A liquid-discharge recording apparatus such as an ink-jet printer comprises: a liquid-discharge recording unit having an emission energy generating device including an electrothermal energy converting device which can heat a recording liquid such as an ink to form liquid droplets in response to an electrical signal, in which this recording unit emits the liquid droplets and deposits them on a recording paper and thereby recording thereon; a recording unit control circuit which can set and supplies the electrical signal to form the liquid droplets to the emission energy generating device in response to a recording signal; and an emission controller for setting the electrical signal to form the liquid droplets to the recording unit control circuit when a power supply is turned on, thereby allowing the recording unit to and emit the liquid droplets in accordance with an environmental condition such as a temperature of the recording liquid. With this dedicated emission controller, the proper emission condition is set and preheating processes and preliminary emitting processes are executed prior to starting the printing after the turn-on of the power supply of the printer, so that the printing state can be promptly and easily optimized by a simple software.
