Trying to come up with a solution for offsite printing, without having to join offsite computers to Windows Server Domain.

I'm a Windows Server 2012 novice and I've just installed a new Dell Poweredge server, running Windows Server 2012 R2 Essentials. We have two different offices in our business complex, each on it's own network/internet connection. I'm trying to come up with a solution for printing from the computers in one office, to the KM Bizhub MFP in the other office. DIrectAccess is not an option, as the offsite client computers run Windows 7 Professional, which doesn't allow for a DIrctAccess connection. They client computers have file sharing capability through Remote Web Access. Is it possible to access the network resources from an offsite computer and print to the MFP through Remote Web Access?

Thank you for your time.
