Missing text or graphics when printing - random with X5

Have discovered a new issue with X5 Recently have begun missing parts of print out. Tried to duplicate but appears completely random.

Output to both Full colour laser and Wide Format printers will miss either text or part of objects. Today printed the text but not the text effects.  
Initially closed and reopened, rebooted, However this has become a now daily feature so regardless tried reprint from the same screen so next print has everything included.

Very costly and time consuming - print preview shows all correct but output is not the same.
