[scribus] images on pdf print at wrong resolution

[GianLuca Sarto]

hello All,

I have a strange issue with a PDF produced with Scribus.

Images are perfect on screen, but print at the wrong resolution.

To be more precise, these images are inserted in a box, automatically 
scaled, but when they are printed, they print at lower resolution and so 
you only see a corner of the image in the box, on paper.

Is there anybody that can point me to the right direction to solve this 
problem?

Thanks for your time,
regards,
-GianLuca
