Abstract
An ink/print media discriminating portion discriminates kind of ink to be used in an apparatus on the basis of information of kind of the ink or a printing medium input by a user. The discrimination information is fed to a thermal energy generation amount control portion. The thermal energy generation amount control portion sets a driving condition, such as a pulse width of a drive pulse or the like corresponding to the kind of the ink represented by the discriminated information, is set in a head driving portion.
Claims24
An ink-jet printing apparatus performing printing on a printing medium by a printing head using a plurality of kinds of inks and ejecting the ink utilizing thermal energy, comprising:
- ink discriminating means discriminating kind of the ink on the basis of information relating to kind of the ink ejected from said printing head;
- driving condition setting means for setting a driving condition of said printing head on the basis of the kind of ink discriminated by said ink discriminating means;
- and
- head driving control means for controlling driving of said printing head for ejection on the basis of the driving condition set by said driving condition setting means.
An ink-jet printing method comprising:
- first step of discriminating a kind of an ink on the basis of an information concerning a kind of the ink to be ejected from a printing head ejecting the ink utilizing a thermal energy using a plurality of kinds of inks,
- second step of setting a driving condition of said printing head on the basis of the kind of the ink discriminated at said first step;
- and
- third step of controlling driving of said printing head for ejection on the basis of the driving condition set at said second step.
