So the paper you're feeding is nearly 2 feet wide? Or is it actually A4 paper in landscape? FM isn't the best for print design projects, but you may be able to get there.
I think you just need to make your layout wide enough by dragging the edge to the right (or using the position tab of the inspector). Maybe print in two columns? Each record will be a page, and you won't be able to check the layout except in Preview.
