Please give us the EXACT message as well as the version of InDesign and operating system.
That said, please note that best practice is to export a PDF to submit to a printer.
What links are you talking about?
Why are you not exporting a PDF and send it to the printer?
Im working on mac indesign 2015, I have created a catalog and need to package it to send it off to a printing company at least thats what I think I need to do, I can save and export as a pdf but Not package the catalog with all the fonts and links in it.. Is it not necessary, Im learning as I go along.
What error messages? What operating system?
