Thanks for posting this code. It helped me develop my own. This allows you to adjust the resolution, and the width of the exported image. It also allows you to print specific pages. Just figured I would post it for someone else's use. Have a great day! import arcpy, os, exceptions, collections

inch_to_meters = 0.0254 #This is the convertion for inches to meters must match the defined coordinate system of the data frame
