One would think that printers aren't much of a security risk, but while this was true a decade ago, it is no longer the case. Samsung's printer line is more or less clearly showing it.
There is a lot of software involved in the operation of today's printers, especially in regard to network connectivity.
Whereas once they needed to get every bit of information straight from the PC through a dedicated cable, printers have their own software now and can perform certain things on their own, especially when they have extra functions like scanning and photocopying.
