Network print not working

[execujan]

Dear community,
I tried to install clawPDF (v0.9.3) on a Windows Server 2019 Standard which function as a print server.
The goal is to install and share it over the network (Windows Domain), so Users can see the printer through the shares.
I've followed the instructions, but I've encountered some problems.

clawPDF-printer is shared and I can install it on a local client through the printserver-share \SERVER.
-> When I try to print a document on the local client, nothing happens (v0.9.3)
-> In release 0.9.2 the clawPDF-printing dialogue was opened on the printserver at the serviceuser, but not on the local client

Client OS: Windows 11 x64
Server OS: Windows Server 2019 Standard x64

I've reinstalled everything multiple times, nothing seems to work.
Did I missed something?

Let me know if you need further informations.

I'm very thankful for any suggestions.

Best regards
