A printing apparatus is disclosed which includes an original positioning device (3) for transporting an original (F) to and positioning it in a printing position, a printing material positioning device (2a) for transporting the photographic printing material (P) to and positioning it in an exposure position, a lighting device (4) for exposing the original, located in the printing position, to print light, an adjustable lens (5) for projecting the original, located in the printing position, onto the printing material located in the exposure position with an variable enlargement, a lens focusing device (6) for varying the enlargement of the lens (5), and a control device (10) for the original positioning device (3), the printing material positioning device (2a) and the lens focusing device (6). In order to produce arbitrary enlargements of sections, the lens (5) is disposed so as to be adjustable substantially crosswise to the transport direction (L) of the original (F), by means of a lens positioning device (12) that cooperates with the control device (10). In order to define a section to be copied from the original and to define a desired enlargement, a control device (13, 14) cooperating with the control device (10) is provided. The control device (10), on the basis of the detail and enlargement defined by the control device, controls the original positioning device (3), the lens positioning device (12), and the lens focusing device (6).
