I have produced a graph , which when I print it I choose portrait orientation in the preview. The page setup is for A4 in portrait orientationwhen I check it in the print preview and it looks fine on the preview screen. However when I print it on my Samsung3405FW in comes out printed on half the page , i.e as if setup for a dual A5 print on an A4 page. If I set the print up in landscape orientation, I comes out on the bottom half of the A4 page filling the width (but page is in portrait, i.e. as though it were printing on an A5 page in the bottom half of the A4 in portrait mode. I have no printer problems with any other progrms I use (Gimp. Office2010,GnuCash, MYOB) so it doesn't seem like a driver problem but something specific to YEd.
