We use Samba also as a print server and after moving the samba directory all printers and printer drivers are not shown anymore in the Windows printer administration tool.

Thanks Rowland

Setting up a new server is not an option for as at the moment because we are running other services on the system that also must be migrated to a new server. 

I've tried to do a test-migration of the server again today like the way i did it before.
It really looks like the only thing that isn't working is samba/cups printing.

When i do a "grep -r '/opt/samba4' /var/lib/samba" i can see, that there are binary files that still includes the old samba path.

These files are:

Is there a way to change the path in this files, or to clean this cache folder? Maybe printing is working after this. 
I think it will save a lot of work, if i only need to fix the print server problem instead of setting up a new server and migrate all services.
