Apparatus for use in printing, e.g. a printed circuit on a substrate (9) comprises a table (4) and means, e.g. pins (40) for sec- uring he substrate (9) thereto, a support (2, 3, 5, 16, 6, 8) adapted to rigidly mount a camera (7) on the table (4) so that the camera (7) views table (4) and a substrate (9) thereon, printing means (15), and means for effecting relative movement between the table (4) and printing means (15) to move the printing means (15) and the substrat e (9) on the table (4) into register. The camera (7) is positioned to view fiducial marks carried by the substrate (9) and printing means (15) whereby to facilitate adjustment of the rela- tive positions of printing means (15) and substrate (9) so that the fiducial marks are in register, thus effecting registration of sub- strate (9) and printing means (15).
