However, I wondered if anyone could tell me whether there is a home A3
printer produced by say, Epson, HP, or Canon, that uses photographic papers
that are as good as those used commercially? Are there any A3 sized
photographic papers that are produced for the home market that are
relatively waterproof and have lasting qualities equal to the photographic
paper used by the expensive commercial photoprinting machines?
Any inkjets that'll match a true photographic print for
waterproofness? Nope, but the closest you'll come for longevity out of
the box may be the Epson wide-body printers with the encapsulated inks.
Other than that, the technologies are different enough (and unproven
since they haven't existed over 15 years) that you won't know until
you've printed and hanged them for years.
Home inkjets certainly won't last more than a few years, so don't bother
with these to start.
www.inkjetmall.com has 3rd archival inks and papers to consider.
Also, FujiFilm Pictrography printers, albeit expensive, do produce photo
prints that will have similar characteristics as regular photo prints,
so that may be the way to go commerically (either get one cheap off
ebay.com or find a local lab where you can send your print jobs).
Longevity of home inkjet printers - forget it!

http://wilhelm-research.com/ (but with a grain of salt since they
changed all of their testing methods after the orange fading crisis)
Realistically, these tests occur in 'ideal' environments and
conditions, and in real life, I would not bet my life or business on any
inkjet print to last more than 10 years (nor provide a warranty longer
than that either). Although you can keep inkjet prints perfectly fine
in cold-storage w/o light (ie. in a folder in a cabnet where some of my
original HP Paintjet prints from 10+ years ago still look fine), once
the prints are out under light and environmental display conditions, you
can toss the longevity thing out the door.
(which is why even Epson offered a 100% full price buyback of the
Epson 870 during the orange fading crisis just a few years ago; which is
why every year, every inkjet printer maker from Epson to Canon to HP
toots 'even longer print life' than the printer they released just 1
year before. Everyone knows that unless it's pigmented or solid-dye,
most of these non-pigmented dyes will fade fast over time.)
Naturally, time will lead to new developments which will lengthen
print life from inkjets, but don't bet a business on it yet.
For the time being, dye-sub (solid dye) printers or FujiFilm
Pictrography printers are the two best alternatives for long-life prints
that should last a decent amount of time (again, don't bet a business on
their lifespans since they haven't been out in real-life as long as film
prints, so who knows the actual stability over 100 years?).
Here, Fujifilm Pictrography prints are my #1 pick -- feels, looks,
and acts just like a real photo print, nothing that would make a client
look otherwise at the paper/medium itself, and superb prints that look
just like film prints.
Step down from there, going cheaper, look into printers using
pigmented/encapsulated dyes such as the Epson Stylus Pro 4000, Epson
Stylus Photo 2200, Epson PX-G5000 (just released in Japan, coming soon
to USA), etc.
If you're doing B&W prints, the B&W Piezography system is the way to
go:
