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. The press roller is biassed by a cam having a profile such that the press roller contacts the drum before the sheet arrives between the press roller and the drum. The cam is also profiled such that the press roller gradually comes into contact with the drum to reduce oscillations between the press roller and the drum.
