Mostly meaningless.
The power of the patent actually makes it LESS likely that there will be DRM
on the printers since the makers of those printers would need to pay a
royalty for the "privilege" of such protection. Since the printers are
generally used for prototyping, who would risk transmitting their designs
to a third party for "permission" to print? The instant a manufacturer
decided to install it in their "brand" they would see their sales plummet.
Now where this "could" be of use would be in commercial stores where
a machine is specifically allowed to only print specific designs to
prevent, for example, a Nike store employee printing a Puma brand
shoe and thus violating copyright and possibly patent laws.
