I'm running Windows Server 2019 on a Hyper-V virtual machine as an RDS server. I've recently rebuilt this VM, so it's a fresh setup. However, I'm hitting a wall trying to install shared printers, specifically USB receipt printers like the Epson TM-T88V, which are connected to workstations using Windows' printer sharing feature. When I attempt to install these printers, I get the error: 'Operation could not be completed (error 0x00000709).' I've gone through a lot of troubleshooting steps already, such as confirming that the printers install fine from other machines, reinstalling the printer locally, using the IP address for the installation, ensuring various Windows settings are configured correctly, and much more. I've even tried different printers and disabled firewalls but to no avail. I'm really at a loss here and would appreciate any insights or solutions anyone might have!

If your workstations aren't on the same domain as the server, that might be a problem. Check your permissions and group policies. It might also be worth considering switching to printers with Ethernet adapters. It really streamlines the setup for RDS environments!
It sounds like you've done some heavy troubleshooting already! Usually, for RDS servers, you just need the driver installed and the server should automatically handle the printers. Have you checked if there's any mess in the registry related to TS Printer Ports? Sometimes old entries can cause issues, especially if they're still hanging around from prior installations.

I've started replacing them with Ethernet ones as they fail, but all my current workstations are already domain joined.
