A printing apparatus includes a printing station, including at least one printhead for applying phase-change ink to the substrate, and a backing member disposed on an opposite side of the substrate substantially opposite the printhead, the backing member causing the substrate to reach a predetermined ink-receiving temperature.

Ink-jet printer using phase-change ink printing on a continuous web

A process transfers an image from an intermediate imaging member onto a sheet of recording media while preserving the ability to duplex print on the sheet. The process includes generating an image on an intermediate imaging member as the intermediate imaging member rotates in a first direction, synchronizing a sheet of recording media with the image on the intermediate member as the intermediate imaging member continues to rotate in the first direction, transferring the image from the intermediate imaging member onto the sheet of recording media as the intermediate imaging member continues to rotate in the first direction, and limiting release agent on the intermediate imaging member to a level that preserves duplex printing capability on the sheet of recording media.
