ABSTRACT:
In an inkjet printer, print image data indicating a pattern of ejection and non-ejection nozzles is produced from print data received from a host computer and the print image data is searched in blocks for an effective block including data indicating at least one ejection nozzle to count effective blocks, wherein a block has a predetermined size. Ink consumption caused by a print operation is detected based on a count of the effective blocks.
