A bio-based polyester thin film substrate for thermal transfer printing ribbon. The bio-based polyester thermal transfer ribbon substrate film has a radiocarbon content of at least 12 pMC. The film exhibits excellent uniformity, handling, and processability, substantially equivalent to petroleum-based counterparts, while being derived wholly or partly from non-petroleum sources.

An inkjet printer includes a printhead maintenance station having a purge station for receiving ink purged from a printhead and an inkjet preservation station configured to contact a faceplate of the printhead with a solvent. The inkjet preservation station maintains the operational status of the inkjets in the printheads of the printer during long periods of printer inactivity.
