My department is using the 2014.2 Release of InDesign CC 2014 (14.2.0). Several users are experiencing repeatable crashes when printing to our Fiery Server.
This only happens when they have a Fiery Feature enabled—such as Duplexing.
Instead of their file printing, InDesign immediately crashes. As a workaround, we Pause the printer, "print" the file and then Resume printing.
What does EFI tech support say? Have you looked at their website?
