Hi mujabad & happy New Year!
At present, soft proof with paper profiles is not fully working yet (should be delivered shortly).
For printing and to keep maximum quality & colour space export your pic as 16bit TIFF with ICC Profile ProPhotoRGB, effective since PL6. Then, in QImage you choose your paper profile and print.
What you can do if you like, choose one of these well known test images, delivered in ProPhotoRGB colour space and containing out of gamut colours. You export such a file in PL6 to ProPhotoRGB as well to AdobeRGB and print both version … to check for differencies after having dried properly.
