     return url + 'print/'

thanks...!

any ideas for this feed?
http://www.electronista.com/rss/electronista.rss

there is a "print" version for every article, but i am not able to determine the "print" link from the article link.

example:
link article
"http://www.electronista.com/articles/10/03/26/geforce.gtx.480.and.470.finally.official/"

print version
"http://www.electronista.com/print/73919"

i am not able to argue the id (in this case 73919)
