From the tiddler's "more" menu, choose "open in new window". Then, from that window, right-click to display the system popup menu and select "print..." Depending upon how your system and printer are configured, you might then see a "print preview" window. Follow the normal steps to confirm and send the output to your selected printer device.
Note: the above steps are for a typical Windows system. I assume that something similar can be achieved when using an Apple or Unix/Linux system.
