ABSTRACT:
A computer portion201of a printer includes a memory storing a printer driver software201aand nozzle profile data211. The printer driver software201aincludes a raster image processor (RIP)203. When the RIP203receives document data209, the RIP203converts the document data209into bitmap data210which is one dot/one bit data for 300 data/inch. Then, the nozzle data converting portion204converts the bitmap data210into driving data212based on the nozzle profile data211. At this time, each bit of the bitmap data210is replaced by 16 bits. That is, the data amount is increased to 16 times of the bitmap data210. Accordingly, fine control of ink ejection can be achieved.
