I've bought printable disks some with a "fast dry" finish which gives a
water resistant finish with pigment inks, and some with a swellable
polymer coating that probably looks good with dye based inks, but smears
easily. TDK printable disks I have seem to be okay.
With pigment inks on the right gloss/semi-gloss paper finish, the prints
are water-proof to the extent that if they get smeared with a little
gunk/sneeze/finger marks when on display, they wipe clean without damage
using a damp microfibre cloth. But it takes a couple of days for them
to dry thoroughly - there's a solvent used (coalescing solvent) to fuse
the acrylic binder and they don't achieve full hardness until it's
evaporated. It also fogs glass if you frame them too soon after printing.

The 1280 technology IIRC dates back to models released around the turn
of the century. Yes they are slow. I don't think the new A3 pigment
ink models (1900/2880) are much faster than the 5YO models they
replaced. Speed could perhaps be ranked in $ of ink per minute they
consume.
