Virtual Channel Gateway is only necessary if printers have to be targeted over RDP, ICA or PCoIP. It enables print jobs from ThinPrint Servers to be sent to the client through a virtual channel of an RDP, ICA or PCoIP connection. This also allows the targeting of printers that can’t be reached over TCP/IP – for example, behind firewalls or with Network Address Translation (NAT).1
Virtual Channel Gateway is installed onto remote desktops (terminal servers or virtual desktops) – while ThinPrint Engine runs on the central print server(s).
1. As an alternative to the ICA, RDP or PCoIP protocols, the Connection Service can also be used –e.g. for local print servers or for gateway appliances.?
