A printer for feeding the sheet intermittently with high precision while preventing a decrease in the print rate is provided. A printer has a feed-in roller for feeding a sheet into a printing region, a feed-out roller for feeding the sheet out of the printing region, a motor for rotating the feed-in roller and the feed-out roller, and a controller for controlling the motor. The controller controls the motor so as to start intermittent sheet feed with a first line-feed-time that specifies a time period for one line feed and vary the first line-feed-time to a second line-feed-time that is longer than the first line-feed-time before the sheet is fed by only the feed-out roller. The sheet is fed intermittently with a shorter line-feed-time while being fed by the feed-in roller which is precisely controlled. On the other hand, the sheet is fed intermittently with a longer line-feed-time while being fed by the feed-out roller which is not controlled as precisely as the feed-in roller. Hereby, the printer can feed the sheet intermittently with high precision while preventing a decrease in the print rate.
