Abstract
A printer for printing out an image formed in a stencil on a sheet. The stencil formed with perforations representative of an image is wrapped around a drum which is made up of a hollow cylindrical support and a mesh screen covering the support. The cylindrical support has an apertured portion and a non-apertured portion and accommodates an inking roller therein for supplying ink to a sheet via the stencil. The sheet is pressed against the stencil by a press roller that faces the inking roller with the intermediary of the drum. A high friction member is located at a predetermined position on the non-apertured portion of the drum or a predetermined position on the mesh screen corresponding to a position where the press roller begins to press a sheet against the stencil.
