Just recently, I've been unable to export or print an MXD that contains the Federal Emergency Management Agency (FEMA) National Flood Hazard Layers (NFHL). I went to FEMA's GIS Web Services site (FEMA's National Flood Hazard Layer) and followed their instructions on adding their service layers as an ArcGIS REST Service.
The layers that I'm trying to show on the MXD is the Flood Hazard Zones. The service layers display perfectly in the MXD; however when I go to print to PDF (I also tried exporting to PDF), the service layers will not print. Has anybody come across this situation?
Maybe it has to do with server limits on the size of the requested data? See Printing and exporting maps containing service layers—Help | ArcGIS for Desktop
I'm not very familiar with server/service issues, so this is just a guess.
