Just download the install files, stop the NPrinting Service and run both of the installation files. In normal circumstances you don't have to restart the server. After installation, start the NPrinting Service from the Services menu or in the NPrinting Server Management Console.
Kind regards, Gerald
We recently upgraded from 16.4 to 16.6 and lost on-demand functionality. It gives us below error. Does the upgrade installer overwrites OSD config file. We checked that port 9000/9001/443 all are reachable from client to server. We made sure that QVW can produce report within Nprinting server. All the permissions are taken care off. It just doesn't work when end user tries running on-demand. Gives below error. When we check log, we don't see any activity for on-demand.
Nprinting on demand service error. Please check if NPrinting service is reachable
