6 Disc printer settings?

[lostpr0ph3t]

Hey guys, I seem to have a problem printing these 6 disc covers all of a sudden. I'm using Photoshop to print my covers and I don't have a problem printing out the single disc covers. When I try to print out the 6 disc it comes out to small. I'm using legal size paper, and I change my printer settings for legal size but everything still comes out wrong. When I use the print preview in PS sometimes it'll show as everything is correct but when it prints out it still comes out to small. The cover sizes are 3370x2160, I'm hoping that maybe one of you guys can help out, or maybe let me know what settings you use when you print your covers out. Thanx in advance guys, I really appreciate any help you guys can offer.
