Dear NPrinting users,
As we always remind our users, it is always important to backup your installation before running any software upgrades. We have unfortunately discovered an issue when upgrading to NPrinting 17.X, if the installation fails for some reason and the install rolls back, it may delete the NPrinting repository. Please ensure that you backup the repository prior to upgrading. Known issue OP-2919, article 000023289.

We apologize for any inconvenience.
Kind regards
Global Support Team
