Comodo Dragon does not print documents on HP Deskjet 3940


The Comodo Dragon browser ( does not print documents on my HP Deskjet 3940.
Instead, when I print a PDF file, the printer just quickly feeds paper through the printer.

I have installed Google Chrome (23.0.1271.97 m) and the same extensions (Adblock, WOT, Ghostery, Mailto:Yahoo! Mail) and am not getting that problem; the documents instead prints as it’s supposed to with Google Chrome. (In addition, Norton Identity Protection 2012.5.6.10 works in Google Chrome!)

I have Windows XP SP 3 (32-bit) installed in the C: drive and am the computer’s sole owner and administrator. Comodo Dragon is installed in the Program Files folder in the C: drive.

Thanks for your help!
