A machine for making printing plates or prints from positive or negative microfilm rolls has a table movable horizontally in two directions to adjust the position of a portion of an electrostatic copier which rests thereon. The copier has a paper cutter, transport, corona charger, exposure positioner, developer, squeegee, dryer and discharge but omits the scanner and associated elements normally employed in such machine. Above the copier is a photographic enlarger having its film holder replaced by apparatus which accurately advances microfilm frame by frame. The image of each frame is formed upon a cut sheet of copy paper at rest on the exposure positioner. The exposed sheet is then developed as the next sheet is advanced to exposure position and the next frame is advanced in the microfilm advance apparatus.
