While the plugin will print to a local PDF printer, if you click on PDF, to generate a PDF, it calls printerfriendly.com and then reports
"We're sorry, but something went wrong.
Unfortunately, an error has occured. We've been notified and should have resolved shortly. If you continue to experience this error, please contact support
Return to PrintFriendly.com"
Tried from IE, Mozilla, MAC and PC, this is a server issue at their site. Cannot use a plugin that makes an external reference call and fails . . .
