Title: Conflict with print pdf module » DOMPDF_Exception: Box property calculation requires containing block width
Project: Hidden CAPTCHA » Printer, email and PDF versions
Issue summary: View changes

That sounds to me like a bug in dompdf. Zero is a valid value for height and width. For print versions, the entire CAPTCHA should be display-none anyway. If you adjusted your site stylesheet to do this, it might fix the problem. The Print module may be able to solve this as well.

Sorry, won't fix because:

1. Indeed that seems like a specific case (the captcha)
2. It seems like it's a bug in dompdf
3. Adding every little fix will turn the code into spaghetti.
