are you a Qlik Sense developer and your sheets you are trying to see in NPrinting are "BASE Sheets"?
You work on application in Work stream and you create sheet A
then you publish your app to Stream XX
then user opens app in Stream XX and creates there his Sheet B in "My Sheets"
then user publishes this sheet to "Community/Published" sheets
Answer - Sheet B will not be visible in NPrinting as it is not part of the Base sheets - it is not a transferable with qvf file (it is only server object which is not supported by NPrinting (to best of my knowledge). In order to to include sheet B in NPrinting developer needs to open application in WORK stream in Qlik Sense hub and create it as a base sheet.
Next important step is to re-generate metadata in NPrinting connection in order to pull new object informations from Qlik Sense.
On the other note - do you use build in QlikSense objects, or extensions? Some extensions may not be supported in NPrinting.
