Publishing via GPO is not working

[TR2NLG]

Hello,

i have successfully set up ClawPDF as network printer on our printserver (Server 2016). The idea was that users are able to print a PDF that is sent via a Powershell script running as process polling the output folder to their mailbox, so every user gets the printed document as PDF attached. That works fine.

Now i am trying to publish the printer via GPO, but the installation fails. I think there is a problem with the driver signing (as they are not signed). When i try to install the printer using the share the system prompts me for evaluated rights, so a manual installation works but is PITA for more than 100 users..

Is there a workaround or did i miss something?

Thank you!
