Abstract
A stencil printer of the present invention is selectively operable in a simplex print mode or a duplex print mode and includes two drums. The drums each has a respective master support on its circumferential surface. The master supports of the two drums are movable into and out of contact with each other without the distance between the shafts of the drums being changed. In the duplex print mode, the master supports contact each other with the intermediary of a paper so as to print images on both sides of the paper at the same time. The printer obviates noise and insures high image quality.
