Not at this time. You don't need to worry about users being able to publish your publication, as this Print-On-Demand service is only currently available for issuu publishers.
As such, only you the publisher can order hard copies of your publications. Readers will not be able to, and they won't see the print icon near your publications either.
When logged into your issuu account, you as the publisher will see the PPOD option/button, but if you log out of your account and refresh your publication page, you should not see the print button.
