Moved to InDesign forum
Print from what? If you aren't licensing ID for the sales staff that sounds like they print from PDF. I don't know anything about Easy Catalog, but I don't think there's any way to edit the PDF using it.
I think you should ask the folks at Easy Catalog about this, and maybe post the question over in ID scripting. It may be possible to write a script that will automatically update the PDF when the ID file is closed or saved, which I suspect is about as close as you are going to come to what you want.

Peter - Thanks.
Indesign is not really in my wheelhouse, so I was hoping there was some type of "ID viewer" etc that might initiate the data update and allow for printing but not allow editing (i.e. full ID license features).
Otherwise, the answer to your question would be yes - PDF.
Will ping EasyCatalog as well and update the thread.
