Microsoft Windows Server 2016 Standard, 10.0.14393 on PowerEdge R530
"Remote Desktop Easy Print" was working until KB5026363 was installed. We confirmed that by restoring a backup before installing the Update, confirm that Easy Print is working and the installing KB5026363 again. After reboot "Remote Desktop Easy Print" stopped working.
The locally connected printers are shown a redirected on the Server, used driver on the server is "Remote Desktop Easy Print" version 10.0.14393.3442. If the device settings are opened, the local printer settings dialog is viewed (for example from Brother or Kyocera) which is the essential key feature why someone wants to use Easy Print so obviously there is a connection between the Server and the local installed printer driver.
But as soon as you start a printer job, for example from notepad you get "Das Handle ist ungültig" in english something like "the handle is invalid".
