You can also use enpi as a lightweight substitute for your word processor in the GUI. Here you see the "source" (i.e. the tag-annotated plain text) being edited with Nedit, the terminal from which you start enpi, and gv showing the formatted output. In the GUI you can usually print out your text either from within enpi or through your viewer of choice.
