Ah, my problem is that I've never seen an 'lpoptions' (or 'lpoptions.conf'?) file. (I don't have any classes yet - just trying to get used to CUPS basic operation before I introduce anything fancy.)
There's no 'lpoptions*' file in my CUPS 1.2.4 installation or its /var directory (other than the lpoptions command and its manual page).
