Title:
プリントシステムおよびプログラム
Document Type and Number:
Japanese Patent JP4321338
Kind Code:
B2
Abstract:
A printing system includes a host computer and a printer. The host computer generates pixel group data for a plurality of pixel groups as print data. The pixel group data is generated in a time series by processing pixel groups aligned in a paper conveying direction within an image forming range. This data provides information for driving specific nozzles in each print head. The pixel group data also identifies non-ejection times indicating the number of times in the pixel group that ink droplets are not ejected from nozzles in succession. By considering the non-ejection times identified in this pixel group data to be "information for driving the nozzles," the printer itself need not count nor identify the number of non-ejection times, but can drive the nozzles with drive waveforms corresponding to the number of non-ejection times.
