Docker CUPS server restart problem

Hello I am using OMV6 server, I have Docker and CUPS installed, the printer has been added to the configuration panel printing from IOS works immediately in less than 10 seconds

The problem appears only when I restart the server then printing takes more than 1 minute, the only solution is:

  • never shut down the server
    -deleting the printer and adding it again in CUPS

Please help what is wrongly configured
