Custom Paper Size

My body width is set to 10. My left and right margins are set to 0.5in. And my page width and height are set to 11in and 8.5in, respectively.

So in essence, I want to print my reports on Letter in Landscape mode.

Yet when I go to print the report and look at the properties, it shows as 215.9 x 279.4 mm Custom paper.

Any ideas?

Thanks.

May have found something. Even though my report is set to 11x8.5 with 0.5 margins (giving me 10in to work with), I found my header, body, and footer set to 10.0000001.

It seems that using snap to grid and the ruler for sizing and positioning add a infinitesmal value which throws off paper selection.
