Tested in 4.4.2.2 and 5.0.1.2 (installed in an attempt to fix the problem)
My documents are designed for A4 , printer is a native A4.
When looking at the fullscreen print preview - everything is OK.
when pressing Ctrl-P - preview is squshed in the left, vertical center of the portrait. not using the whole page.
As if top, right and bottom margins were ~33%
This happens when printing to paper, or exporting to PDF.
