Mate - before you create a topic please use the brilliant feature of this community called: SEARCH.
I have answered this question probably 2 or 3 times already and others did so too - Correct andswers are in below links!!!
Please also note that when you address issue and you call it "NPrinitng Issue" like in your title you make it generic and extremly hard for all of us to know what is your question about and you make it difficult for others to use a search in Community.
Next time when you start a topic in community please provide a descriptive title like for example. " How to apply different user filters to different reports in NPrinting 17.X.X..."
When applicable please mark the appropriate replies as CORRECT. This will help community members and Qlik Employees know which discussions have already been addressed and have a possible known solution. Please mark threads as HELPFUL if the provided solution is helpful to the problem, but does not necessarily solve the indicated problem. You can mark multiple threads as HELPFUL if you feel additional info is useful to others.
cheers Lech, When applicable please mark the correct/appropriate replies as "solution" (you can mark up to 3 "solutions". Please LIKE threads if the provided solution is helpful to the problem.
