I am using the latest version of ChemDraw, but when I print from my word processing document, I get a PostScript error.
The structure has either lost the necessary PostScript or never had it in the first place. Copy and paste an offending structure out of your word processing document and into a NEW ChemDraw document. Copy and paste the structure from ChemDraw into a NEW word processing document, and print. If this works, do the same procedure for any remaining offending structures. You will also want to copy the text from the old word processing document and paste into the new document. After the process is complete, you should have a new word processing document that does not give any PostScript errors when printing.
