So that can be set using IMPORT on the "add" action?

I think this is what's required then:

1. udev-configure-printer:

C program
udev invokes it with IMPORT+="..." to remember Device ID

Operation:

Fetch Device ID
Decide whether we have a queue configured
(Note, during boot cupsd may not have started yet so we'll
need to retry)
For ACTION=="add":
    If queue configured but disabled (by us), enable it
    If queue not configured, invoke udev-add-printer (see below)
For ACTION=="remove":
    If queue configured and enabled, disable it

2. udev-add-printer:

Python program (so it can use cupshelpers)
"Add printer" parts of hal_lpadmin
