Similar to ShareThis module, the Printer, the e-mail and PDF versions module create the Print, Email and PDF buttons on you node page.
Installed module and you can now modify its settings @ Administer –> Site configuration –> Printer, e-mail and PDF versions.

 

I have just set the Link Style to Icon and Text. Check it out in any of your node.
