Hello All,

I have this problem in both CentOS 6 and 7, with standard Firefox, version 31.6. I’ve tested this with Zarafa and Zimbra webmail.

Certain mails cannot be printed. These are mails that have “untrusted” images somewhere in the body of the mail. As a workaround : If you forward the mail, and before you press send, you delete these images, you can print them. I hope I’m explaining this right.

Note : if you ever wonder what a bunch of people complain about the most when you put them behind Linux machines, it’s printing. Probably they all of a sudden they cannot complain any more about annoying pop-ups or viruses shutting them down completely.

I see this Em in /var/log/messages :
