Hello,

If you go to the Print dialog, Image settings, and push the 'Adjust Page Size and Position', then when you go back under the Image settings, all parameters on this page are no more modifiable. Result: you can't print a full landscape image.  

Detailed example:
For example, create a new image in full landscape size (10x7 inches for A4) and draw something that will be shown on the print preview.
Next: go to the 'File, Print, Image settings' screen: you see that the image will be printed on portrait page. Then push the 'Adjust Page size and Orientation' and select Landscape, then go back on the 'Image settings' screen. The page is now on Lanscape format, but you can't modify the dpi settings to fit the page. The only thing you can do is to close this option. Or print using dpi calculated in portrait mode...

This has been constated on Windows 2000 and Windows XP.

Best regards,
