Printing Help!

[Lorelei]

Hi guys, I originally posted a different problem, but I sorted it out so I thought I might as well edit this post with my new problem! So I'm printing via the PowerDriver printer after following the sawgrass set-up on Photoshop and I can't seem to get a decent printout. The colour I'm printing is mainly grey and I'm almost getting something maroon like, with random white outlines that I didn't even have in the image. Do I need to change any specific settings? Thanks for any help!
