Synthetic paper for Epson 9880 (or Canon iPF 8400s)?

[mwc]

Bossman wants to try printing on a synthetic stock on our Epson 9880 or Canon iPF8400s.
I have personally never used other stocks than coated paper on these devices, as we are using them primarily for color managed pre-press proofing only.

My question to those with experience...
A. Is this possible on these engines, knowing that they are not solvent or UV printers...just using "Aqueous?" pigmented inks?
B. If A is possible, do you have a recommendation for a stock to try?
C. If you gave answer to B, can you print both sides of this stock?
D. If any of this is possible...would you say this would be a water-resistant print?...say something hanging outdoors, but covered by an awning, little direct sun, and occasional rain spray (or what would you say about the durability of such a print?)

I'm asking 'cause I don't know, please feel free to post candidly....thanks!
(my gut tells me that these aren't the devices for this type of print....but...)

My experience with Epson printers is they do not like any paper other than epson paper.
The ink will not dry and you will have what is known as "ink pooling" (ink that does not dry or not absorbed and then smears).

Same here, they use to make me run different sheets thru my old proofer
I had to do a ridiculous amount of cleaning.
With my new proofer, I say NO!
I see they have a lot of different materials
As long as it is made to run thru the Epson, It might not be a problem
paper vendor might give you samples?
