This line is a mere string too:

udev-configure-printer "$IEEE1284_ID"

You'll now point out that double-quotes are needed to keep the
environment variable expansion in a single word for the argument vector.
That's what single quotes are for. :-)

ACTION=="add" RUN+='udev-configure-printer "$IEEE1284_ID"'

but I don't think udev understands that syntax.  My point is that it
ought to have been made that way.

In other words, a command line is a string that can be picked apart into
separate words for an argument vector, by the shell or by wordexp().
The way to pass in arbitrary strings safely is with properly quoted
environment variables.

Probably the best idea for now is to use your suggestion of reading %
p/ieee1284_id from the file system.
