In a support case today, a partner wrote that Business Central Print does not support Duplex, based on information from this article: OnAfterDocumentPrintReady Event – Business Central | Microsoft Learn
After having a closer look, there are even more things not supported by Business Central: default copies, color, duplex, and custom paper trays/bins. However, ForNAV Direct Print on Business Central supports all of these.
More advanced features such as stapling, punching holes, folding, and so on are also supported with ForNAV Direct Print, because these advanced properties can be specified in the printer setup from the Windows control panel.
In addition to this, ForNAV Direct Print also supports printing native ZPL, which enables hardware features such as full/half paper cutting and RFID chip programming on Zebra receipt and label printers.
