Apparatus and method for printing on a container

Abstract

A printing system that allows printing directly on surfaces of random-height packages includes features to adjust the height of a printer to accommodate differences in heights of different packages. A macro adjustment of printer height may made of the printer relative to a frame. A conveyer, for example a high-friction belt, moves the package into a printing region between the printer and the belt, where the printer prints information on the package, such as address information and/or other information that might normally be printed on a label. The printer height may be adjusted by a lifter that raises the printer relative to the frame to an individual height suitable for printing on that package. As the package passes through the printing region the printer may be maintained at that individual adjusted height suitable for that particular package.
