Abstract:
According to the embodiment, a printing apparatus includes: a printing unit that forms an image on a web; a first feeding unit that feeds the web; a second feeding unit downstream of the printing unit in a feed direction; a buffer unit that has a buffer plate and absorbs flexure of the web generated by the two feeding units by operating the buffer plate; a first feeding control unit that causes the first feeding unit to execute a first deceleration operation; and a second feeding control unit that causes the second feeding unit to execute the first deceleration operation when a trigger for stopping the feed of the web has occurred, measures a feed amount of the web fed by the second feeding unit, and changes the first deceleration operation to a second deceleration operation based on the feed amount.
