After being disappointed in the printed output from a color xterm screenshot, I generated an XSLT/FOP stylesheet that dumps out color pdf, suitable for printing. I include the wrapper (for running it on a debian unstable system -- note that I haven't found anywhere to get the w3c.jar other than the upstream FOP sources, nor anywhere else to find org/w3c/dom/svg/SVGFitToViewBox...) and the stylesheet here, for your enjoyment; do whatever you'd like with them. (In practice they need more tuning of the colors, and I left out margin settings altogether.)
