A configuration for printing striplike print carriers in a postage meter and/or addressing machine, includes contact-pressure elements secured to a revolving conveyor belt for transporting the print carriers upright and in contact with a guide plate having a printing window. The contact-pressure elements are movable resiliently toward and away from the guide plate and the print carriers are printed by an ink jet print head located behind the printing window. In order to expand a range of use, increase reliability and make it possible to selectively print not only letters but also postage strips or address labels, a strip magazine in an entrance region of the otherwise conventional print carriers, a guide part which is disposed in an insert and is initially concave and then convex in shape, and a spacer part in the printing window, which is adapted to a jet distribution, are disposed at the level of the printing window. The strips are therefore guided essentially centrally along the printing window and above the conveyor belt by the contact-pressure elements, to assure uniform utilization of a printing field of the strips and prevent information losses.
