I do not have that particular printer but it should print plenty dark.
Basically to get it to print dark, you need to change all of your print settings to lay down more ink, AKA set paper to extra glossy photo paper and indicate that you are printing a photo not text.
Also make sure you are printing on waterproof film, 5 mil preferably.
It should be a very simple fix with a little experimentation.
