When a file does not print or just parts do not print it can be a corrupt page. An occurrence seen with Adobe Illustrator and Corel DRAW is corruption of the actual document (page). When a file is sent to print and it flushes out of the RIP or just seems to disappear it can signal a PostScript Error.
First look at the art in how it was colored or built. Many artists use templates for setting up art with registration marks, etc. Repeated use of the same page, copying and pasting graphics in and out can lead to a PostScript Error for the page.
Copy and Paste the art file to a NEW page. Convert fonts to outlines/curves. Then see if the file prints. Simply a fresh page can resolve the PostScript Error.
