Well here's the problem.
1. The printer is on the network, and not physically attached to the Host, Guest VM, or the computer that's initiating the RDP connection.
For you to print from the VM. You'll need to either
1. Install the network printer to the VM assuming they are on the same subnet.
2. Install the printer to the computer you are RDP'ing from.
I would go for option 1. If it's a production VM, it should be set to bridged mode so that it's just like another computer on the network. It will get an address from your DHCP like a physical computer at that point.
