Menu path: Setup > Sessions > RDP > RDP Global > Mapping > Printers
In this area, you can configure printer mapping.
Enable Client Printer Mapping
☑ The locally connected device printer is made available for your RDP sessions, provided that it was not disabled on the server-side. (default)
The printers must be set up on the Devices > Printer > CUPS > Printers page and must be enabled there for mapping in RDP sessions.
Because the device merely places incoming print jobs in a queue, you need to install the printer on the server.
