Cut you image into several sub-images, that each fit on a 8"x10" sheet. Remember that you print likely has margins (there is almost at least one at the bottom of the sheet).
OTOH the image you show looks very pixellated... and 36"" at a decent print definition (150PPI) is quite big (5400x5400px). This would be better done with vector graphics (i.e., InkScape).
