When I print a document from ChemDraw, some atom labels or captions are missing or they appear as a black box instead of ledgible text.
We have found that some printer drivers can cause rotated text to disappear under Windows 95. Check with the manufacturer of your printer to ensure that you are using the most recent printer driver. If you are not using the most recent driver, try updating your printer driver to see if that fixes the problem.
A temporary work around is to copy and paste the entire ChemDraw structure with the rotated text to another program, like a word processor, and print from there. If you are using a PostScript printer, you could also save the ChemDraw file with the rotated text as an Encapsulated PostScript file (*.EPS), and then insert the EPS file into another application and print. An EPS file will give you the highest quality output to a PostScript printer. (MS Word is a good application to try this with. To insert an EPS file into Word, choose Picture from the Insert menu in Word. Set the File Type to EPS, and choose your ChemDraw EPS file. )
