That's what I suspected, when paper size is in Inch and drawing in mm, this was probably not considered in the contribution for this feature.
You can test if a metric paper size like A4 works or set a custom paper size where you enter 8.5x11 in mm.
More efforts might be to scale the drawing down to inch, to match the imperial paper size.
Dividing 1414 width by 8.5 paper width results in 167, what is over the limit. This also means, that the unit mismatch will lead to a much too big drawing anyway.
Another idea, I just had writing this, is to change the printing factor.
When the drawing is 1:1 in mm use 25.4:1 factor for printing on imperial paper, this might work without changes in the drawing and print settings. Can't check this right now, but I think it can work.
