I can answer my own question here.  If I specify it in the printcap
like this:

lp:
    :rp=lp:rm=host1:client

...then it works as I would expect, but this:

lp:
    :lp=lp@host1:client

...doesn't work (I'd thought they were basically one and the same).  I
have tried specifying force_localhost@ in the printcap entry, but this
makes no difference.
