/usr/local is where system administrators can install printer drivers
(say, downloaded manually from linuxprinting.org), and /opt is where
vendors can install printer drivers (say, installed via an LSB package
downloaded from the vendor's website) that aren't shipped as part of
the operating system. Question: Is /opt/printing consistent with the
FHS? Wouldn't it be /opt/<vendor>? Yes, that means there's no
canonical place for vendors to drop printer drivers so they
are available system-wide, but that's the equivalent problem of
not having a single path element for third-party
executables, and should presumably be solved in the same manner.

(Adding lsb-discuss to this discussion, so we can get FHS feedback.)
