During the discussion I asked this:

Is this possible with CUPS?

Then CUPS could work as spooler and filter when the exact printer
capabilities are only discovered at the moment when the user selects the
printer for a job via the print dialog. cups-browsed creates only a raw
queue on the Bonjour discovery of a printer to avoid waking up the
printer and complete capabilities are polled via IPP only if the user
selects a printer in the dialog and the dialog has to show the option panel.
