I am trying to export the image from ARCGIS PRO, but it is indefinitely exporting exporting exporting ..........
Apologies that you're experiencing this issue. Do you see the same error message when exporting as a different file type? Can you try to export it to a different folder? Finally, can you see if you have a highly detailed layer in your map that you are attempting to print--this may increase the time needed to render the print.
