All of the new destination APIs, including:

    cupsConnectDest
    cupsCopyDestInfo
    cupsEnumDests

Don't create queues until you use/select a printer.  Trying to shoe-horn the former 1990's CUPS browsing experience just exposes the problems with that browsing experience in 2013.

A create-on-first-use approach allows you to list (but not wake up) local printers. And then the queue you create can be full-function, wake up the printer you are about to print to it, etc.
