Hello,
Please check the driver used on the Server side. Generally, the printer will be redirected to the Remote Session using the driver Remote Easy Print which is preinstalled in all Windows Servers
Group Policy must be correctly set to enable Remote Easy Print on the Server. The policy location is “Computer Configuration -> Administrative templates -Windows Components -> Remote Desktop Services > Remote Desktop Session Host -> Printer Redirection”.
The setting “Use Remote Desktop Easy Print printer driver first” must be set to “Enabled” for Remote Easy Print redirection, and it has to be “Disabled” for Legacy Print. For “Not configured”, Easy Print is chosen by default.
If the policy mentioned is disabled, the Remote Sessions established will use the print driver set in the client machine as preference, the print jobs can be affected with issues such as slowness, graphics, and others since some drivers might not be functional under Remote Session configurations.
