I am new to large scale printing from ArcGIS. Our school recently purchases a 36 inch HP Designjet T520. I have been able to print some jpg and pdf files successfully but have not had as much luck from ArcMap. Specifically, I would like to print a map I have designed that is 36" x 72". I have not been able to set up the correct orientation. Any suggestions on what settings to use would be greatly appreciated.
