Abstract
When it is assumed that an expected maximum temperature change from a reference temperature during usage of a printer is Δt, an ink landing interval corresponding to raster resolution on a recording medium in a head main scanning direction is P, a maximum distance between nozzle rows of recording heads on a sub carriage is L, a linear expansion coefficient of a linear scale is α2, and a linear expansion coefficient of the sub carriage is α1, L(|α1−α2|)Δt≦P/2 is satisfied.
