Abstract
The present invention provides a serial printer and a printing method using the serial printer. In the serial printer, assuming that the number of driven nozzles arranged in a secondary scanning direction on a print head is n and a nozzle pitch is a k-dot pitch, k is set to an integer which is no greater than n and has no prime factors greater than one in common with n. Further, secondary scanning is performed at least once at each of the start of printing and the termination of printing using a paper feeding distance of an m-dot pitch. On the other hand, secondary scanning other than the at least once secondary scanning is performed using an interlaced printing paper feeding distance of an n-dot pitch. In this case, m is an integer which is less than n and has no prime factors greater than one in common with k. Preferably, m=k.+-.j, wherein j is an integer no less than 1 and less than n.
