Access issue can't display content to print pdf?

I'm having some issues with this module.

First of all I just wanted to say this module is perfect in all ways and probably the best pdf / printing solution for online sites!
except for one problem that I'm having: I need help figuring out how to allow PrintFriendly to get access right to a different module (it's called node premium)

Node premium locks down content only for specific roles to view the content so when I add the print friendly button on this type of pages/content it doesn't display the "premium content". If people that do not have specific roles/subscription click on my premium content they get prompted with the option to buy subscription so even if I'm the admin trying use print friendly option/button it only shows me the message I generate for people without subscriptions I think it's because when I'm trying to print or edit the page after clicking the print button it takes me to: https://www.printfriendly.com/p/g/8tvn8P which is not a authenticated user on my site and that's why it fails?

Please share some suggestions I really need to work this out quickly.

Thanks in advance good people! :)
