Digital BW, The Print

Hello,
Pardon my ignorance, but I'm not quite sure what process hot dry
mounting involves.
Anyway, I'm just in the process of getting information on how to mount
digital prints. Or to state it more precise:
How do you mount a 44 * 12 " photograph? A friend bought two of these,
one for her, one for me. It's printed on an Epson 2100, don't know what
paper, I think EAM (?), but the back doesn't say anything, just plain
paper (from a roll).
My friend wants to glue her copy to a piece of MDF (woodboard). What
glue would you advise, what would be definitely be avoided? (I am still
doubting about what the best way is to mount is, without having to shell
out four times the price of the photo for an expensive frame).
TIA,
