JKT - Thanks, you were right. When I put a check in "Use printer margins", the margins are "reset" to zero, and the entire 8-1/2" by 11" page displays as a full canvas.

The information in the OmniGraffle help content on this feature is pretty scarce, but I take it to mean that when you enable printer margins, you automatically give the printer free rein over the margins, even though the canvas shows the entire sheet of paper and lets you draw on the whole thing.

On the other hand, when you disable printer margins, you are telling OmniGraffle that you want to set the margins yourself, which may or may not coincide with what the printer's printable area is.

Would that be a fair assessment? (I guess I could test this out with a PDF to see...)
