Microsoft licensing / printer sharing

Server 2012 will share a company printer for general use.  The 40 computers assigned to users in AD will use it.  Additionally, 20 computers that are not on the domain would also need to use the printer which is shared off the server.  
The non domain computers  would authenticate to the server using an account in AD.  But the Server is licensed under device CALs.  Would we need an additional 20 Device CALS for the computers not on the domain to print?  

We may try to utilize direct printing if 20 additional device CALs are required.

Yes, as I understand licensing you would either need a device CAL for EACH system (since authentication and use of server resources is being done) OR the users using the computers would need CALs (you can mix and match).  If you want the management features/ease of a networked printer, you need CALs, otherwise, you can go directly to the printer and skip the CALs - but then you have to go to each computer for that.  

DISCLAIMER: Licensing advice offered here is a "best effort" and based on the understanding of the respondents. Licenses can change and we may not be aware of these changes or may misunderstand them. Further, licenses and laws allowing them to be enforced can differ by country and/or region and what we understand to be true in our area could be false in your area.  "they told me on Experts-Exchange" will not be a valid defense in a software audit.  All licensing questions should be confirmed with the appropriate licensing authority (the maker of the software/issuer of the license).
