Re: [Printing-architecture] high delay while printing

Hello Doug,

sorry for the late response.

Thank you very much for your help!
Now it works like a charm.

But I still don't get it.. You said URF is prioritized, and will be rendered by cups, but why is it so slow? It's a potent VM with two cores.

best regards
Stefan
