We released PaperCut ChargeBack 5.1 today. Most of changes are under the hood. The release incorporates a new WebTools interface file layout to help facilitate “skinning” the visual layout. This is aimed at businesses that wish to integrate PaperCut into their existing intranet sites. The release also includes an updated “Page Counting Machine” supporting additional printer languages such as ESP/PAGE-COLOR, PRCS from Ricoh and improved support for other printer languages.
The knowledge base article Supported Printers gives a good overview of compatibility with popular printer brands.
