Can't find the names of IPP print queues

I have (several) non-CUPS IPP printers; however, I cannot for the life of my determine the names/paths/whatever of the print queues. :631/ and :631/printers/ are completely unhelpful or return 404. I have no clue how to print to these printers, but OS X and Windows seem to have no problem automatically discovering the names of the print queues (although they won't expose them to me). On Linux however, (and I have searched and searched), I am at a loss. As soon as I get the names of the print queues, I know exactly how to print. Printing on Linux has become so frustrating to me when my print servers aren't running CUPS.
