How do you output an info page to pdf?

http://unix.stackexchange.com – If man -t ls | ps2pdf - > ls.pdf is useful for outputting the ls man page via ps2pdf to pdf, what about info pages? I've tried something like the following but with no success: info -o info | ps2pdf - > info.pdf All this does is output a blank pdf file called info.pdf and output the body into a text file. (HowTos)
