Printing Normally Using High Contrast Black?

I use High Contrast Black as my theme. In the past, when I would print a document, it would print normally, i.e., black text on a white background. Some time ago, tho, my printer began to print the document as white print on a black background! But here is the strange thing: if I copy and paste my text to Notepad and print, it prints normally as black on white. Both Word 2010, Jarte, and Wordpad will NOT print normall, and I cannot find settings to change this behavior. Please note that to the best of my knowledge, I did NOT change any settings to cause this printing anomaly to begin. HOw can a person using the High Contrast BaBlack teheme arrange it so that documents print out normally, black text on the white sheet of paper?
