Patent number: 9789718Abstract: When performing printing for every M columns, a print buffer stores printing data by dividing the data into M groups. When data is multilevel data or when performing no column thinning printing, the print buffer stores the data without dividing it. When data to be stored in the print buffer is binary data and printing is to be performed for every M columns, printing data is stored as it is divided into M groups, and these data groups are read out as they are switched for each scan of the printhead. When data to be stored in the print buffer is multilevel data or when performing no column thinning printing, data is read out without switching readout regions.Type: GrantFiled: May 19, 2016Date of Patent: October 17, 2017Assignee: CANON KABUSHIKI KAISHAInventor: Hisanori Inayoshi
