Adding a wait loop might be a nice extra safeguard, so I could consider adding it, because safeguards are always a good idea.
Adding cupsenable or cupsaccepted seems like a much better idea, though, IMHO.
However, the problem with queue creation has been confirmed to be caused by the unnecessary -E that used to be present in one lpadmin stanza in postinst. All other occurences of lpadmin that did not use -E always worked as intended.
