ABSTRACT:
A print head 2 has multiple nozzle groups 2a, 2b spaced apart in the sub-scanning direction by a prescribed inter-group distance pn.sub.i. Each nozzle group 2a, 2b has multiple nozzles aligned in the sub-scanning direction at a nozzle pitch k. In a first printing scheme in which the nozzle groups record different raster lines, the inter-group distance pn.sub.i is set to a value different from the nozzle pitch k. Since the nozzle pitch k need be secured only within the nozzle groups 2a, 2b individually, a print head 2 with many nozzles can be readily obtained. Interlace printing can be effected by selecting the total number of nozzles N, the number of nozzle groups M, the number of scans S and the nozzle pitch k to make N/(M.multidot.S) and k/M relatively prime and effecting sub-scanning at a constant pitch of N/S dots. In a second printing scheme in which multiple nozzle groups record every raster line, the selection is made to make N/(M.multidot.S) and k relatively prime and sub-scanning is effected at a constant pitch of N/(M.multidot.S) dots.
