The Linux version of Eclipse doesn't support printing. The alleged reason is that printing is so flexible in Eclipse that no one could agree on a suitable subsystem, especially considering that the Linux version has 2 different graphical toolkit versions (gtk and motif).
The way around this impasse is to use the Tools menu to define your own print tool of choice. The simplest one, of course, being just to run the lpd program on the currently-selected file.
