Abstract
A printing device includes a nozzle for discharging liquid, a counter that counts the number of signals for defining a cycle in which the liquid is discharged through the nozzle, and a discharge control portion that controls such that the liquid is not discharged through the nozzle when the number of signals counted by the counter is larger than a predetermined threshold value.
Claims7
A printing device comprising:
- a nozzle for discharging liquid a plurality of times onto a print medium during a liquid discharge cycle, wherein said print medium is transported in a transportation direction, and the liquid discharge cycle is defined by a scanning path movement of the nozzle in a main scanning direction different from the transportation direction;
- a counter that counts the number of pulses of a control signal that indicates an initiation of a discharge of liquid through the nozzle in a current liquid discharge cycle;
- and
- a discharge control portion that halts all discharges of liquid for the remainder of the current liquid discharge cycle when the number of pulses of the control signal counted by the counter in the current liquid discharge cycle reaches a count value larger than a predetermined threshold value.
