Maybe a bug?

In ZD 2.0 GA (b10580) Nobody is able to print email from shared mailboxes. I can remember that this has been an issue in ZCS-6.0.7 and ZCS-6.0.8 and that it has been patched there.

The problem occurs in both the Windows as the Linux version

There is a similar bug related to printing shared contacts.

Bug 51451 - Printing shared contacts gives HTTP Error 500

Can you take a look and add relevant details to the bug report?
