Joseph, I took a closer look at how PDFBox is rendering this file, the text in question is being rendered using AWT, which Java passes to the printer as a (PostScript?) text drawing command. It seems that your printer driver always draws the text in back, so what you’re seeing is probably black text on top of a black box.
I think I might have a workaround for you, instead of passing the vector drawing commands to the printer driver via Graphics2D we can make PDFBox render the PDF itself into a BufferedImage and then send that rasterised image to the printer driver. This might be slower and use more memory, but it is guaranteed to produce the same result as PDFBox does on the screen. I've added a new constructor to PDFPrinter in revision 1586802, which accepts a dpi parameter. If you set this (e.g. to 300) then the printed output will be rasterized and sent to the printer as a bitmap, instead of the usual vector graphics, which should bypass your buggy printer driver and its text rendering. Let me know if it works.
