Microsoft has for some reason prevented the possibility of redirecting some peripherals on its server operating system.
We do not have an extensive list of all the peripherals that cannot be redirected thought.
Therefore in this case it is recommended to use Windows 10 Pro instead of Windows server xxxx.
You will below the general information on how to redirect peripherals and printers:
Using standard redirection can be tricky, because many prerequisites must be met in order for it to work. Printer and peripherals redirection is not supported with the use of HTML5 and the TSplus Mobile App.
You need to install the exact same version of device drivers on client side and server side.
This means if your server is installed with 2012 x64 but your client computers are installed with Windows XP x32, you will need to add manually these drivers on your server by editing the print server properties and add x32 drivers for XP.
For best results, if you are still using Windows 7 / 2008 operating systems, it is also recommended not to use USB printers but prefer COM or LPT printers.
If you are using USB printers and peripherals, make sure you updated the RDP protocol of your client computer to 6 or above to ensure maximum compatibility with redirected printers.
Even with all this in mind exotic printers and peripherals may not be suitable to be redirected in a TSplus session, therefore you may need to look into specific procedure to install these printers in RDS / terminal server environment, which is very close to TSplus in this case.
