Abstract
Techniques for pausing and resuming printing operations in mid-plot while reducing visible artifacts. A pause row/swath location is determined at which printing is to be paused. In one pause/resume mode, printing of all rows and all pixels from commencement of printing through the row location is completed, and no pixels in rows immediately following the row location are printed. The printing is paused for a time interval, and operations such as a pen refill can be performed. Printing is resumed at a resume row location immediately following the pause row location to print only rows following the pause row, wherein wet ink is not applied to locations printed prior to the pausing. In another pause/resume mode, in a multi-pass print of an image, the pause occurs upon completion of a pass without completing all printing prior to the pause row. Following the pause interval, printing is resumed, as though a pause had not occurred. The pause/resume mode is selected in dependence on print parameters, including media type and print quality.
