ABSTRACT:
A variable working distance photographic printer receives paper from a supply magazine through a first fixed opening and supplies the exposed print paper through a second fixed opening to a take-up magazine. The variable working distance is achieved with a movable paper deck within the photographic printer. Variable guides are provided between the first and second fixed openings and the movable paper deck in order to accommodate variations in the position of the movable paper deck. Variable working distances are provided, therefore, without requiring that the supply and take-up magazines be movable.
