Abstract
A method and structure are provided which allow a print pass to be initiated even if a swath buffer in a multi-pass printer has not stored enough print data to utilize the full printhead. In one embodiment, if the swath buffer is full, a print pass is initiated using the existing print data in the swath buffer, which may result in using less than the full printhead. By allowing a print pass to start when the swath buffer is full, problems such as inconsistent, delayed, or interrupted printing are minimized or eliminated. In another embodiment, if a certain period of time has passed since a previous print pass, a print pass is initiated using existing print data in the swath buffer to print new rows and to print over previously printed partial rows to minimize hue shifts.
