Abstract
The present ink-jet printer is of the type in which ink droplets are charged under control and deflected by passing through an electric field, and it has two modes of operation: deflection error compensation mode and printing mode. In accordance with the present invention, deflection error is first compensated to determine an optimum amplification gain, which is then used in the printing operation, in which interactive effects with other ink droplets are compensated as well.
