There is no specific sharepoint connector for distributing NP reports.
However, if you create network share on the sharepoint server and use that as an NPrinting folder "Destination" you can use that Destination folder for report distribution. The sharepoint server can use that share from which NP reports can subsequently be consumed via the sharepoint server.
See the link below regarding NPrinting Folder Destinations.
NOTE: it is critical that the NP service account has full read/write permission to distribute reports to the destination folder
