've been printing with great results. Somehow I reset a setting that when Qimage is showing the layout in landscape it will print portrait.
Sounds like you changed something in the driver. You need to mention the paper size, print size and printer type.
Not having any of this information, I would suggest that you check the preview screen upper right of the main screen, and if all looks right, then click on the tab below called Print Queue.
On there you will see the size of the print and the landscape print will have the horizontal size first. Example: and 8 x 10 print in landscape will be 10 x 8.
If you click the portrait orientation it will say 8 x 10.
If all looks right, then I suggest go to HELP and click on RESET PRINTER.
I am assuming the page is changing, not the image on the page...
