A WMS request include a bounding box (in CRS units) and image size (in pixels). I guess QGIS determines the bounding box from the map extents and the image size from the screen (or printing) resolution. I tried with WMS "Property" -"General" "Visibility > depending froms scale" but nothing changes.... > Furthermore, when I prepare a Printing with the same WMS, I usually can't > keep the same scale I was using in the project.

Usually a printed map needs a bigger image than a screen one so you can see the image in the screen but maybe not in the printing. I often download several images and use virtual rasters to compose a bigger one in order to workaround these limits.
