Abstract: The inkjet printer (10) includes a carriage for holding a substrate (T) to be printed, movably supported along a printing path. The carriage comprises a slidable tray having lateral edges (31?) defining a reference printing plane, and a vertically movable support table (32) for the substrate (T) and a lifting device (33) conformed to move the support table (32) between an upper position above the lateral edges (31?) of the tray (17) for positioning and removing the substrate (T), and a lowered position beneath the lateral edges (31?) of the tray (17), in which the support table (32) and the substrate (T) are urged against a stop frame (18) removably connectable to the tray (17) to keep z printable surface of the substrate (T) in a printing plane defined by the lateral edges (31?) of the tray (17).
