A printed sheet delivery device (3) for a printing station (1) includes a collection tray (7) reciprocatable by a transverse-displacement drive (6) for receiving and sorting sheets (2) in stacked, printed-side-down relation in transversely staggered groups (4a). A housing (9) separate from and releasably securable to the printing station (1) is formed of a lower housing part (9a) within which the transverse-displacement drive (6) is mounted and an upper housing part (9b) that is contoured to define the collection tray (7). Slide guides (14a, 14b) carried on the bottom (13) of the upper housing part (9b) on both sides transverse to the direction (5) of sheet delivery cooperate with guide ledges (25, 26) on the lower housing part (9a) for guided transverse reciprocation of the upper housing part relative to the lower housing part.
