a device for printing a print carrier in the printing region makes use , in a force transmission region , of a driven transport drum and non - driven back - pressure rollers or , alternatively , of a non - driven back - pressure conveyor belt . a stationary ink - jet printing head prints , in the printing region , the print carrier that is moved downstream , the ink - jet printing head being disposed axially relative to the transport drum . the printing region amounts preferably to about 1 inch and is at a distance from the force transmission region , the distance of the furthest pixel from the edge of the transport drum , being smaller than the radius of the circumference of the transport drum .
