Abstract
A printer including at least two tractor unit mounting sections upstream of the print position in the sheet feed direction, and at least one tractor unit can be mounted on either of these tractor unit mounting sections. The sheet feeding direction can thus be selected freely in accordance with the web replacement frequency or the printer installation location merely by changing the mounting position of the tractor unit. If the number of tractor units is increased, a plurality of webs can be set up simultaneously and used selectively.
