Dear Mikkel,

Are you suggesting one should use the ipp:// URI rather than http:// ?
I always use the http one, on the grounds that I've heard of http .
Is there really any difference?
I assume one is not really using http, just the protocol.

It's a pity CUPS gives an inordinately long URI for USB printers.
