First allow me to make sure you do not have invert or negative selected if your background is printing black. What is the original color suppose to be (white or nothing I assume)? Meaning, you haven't selected for it to be red and it is coming out black, correct?
What color is the text printing out as? If the background prints black and text is white or if the image looks mirrored, you may have to double-check your print options page does not have negative printing or mirrored image selected.
If that does not help you, let me know and I will see if this is similar to newrg80211 who experiences this with different .dpi's as well as it possibly being a setting in Adobe.
