Hi, when using the BarTender Mobile app, I try to add a BarTender Site but I get stuck on the Printer Router URL with the message in red 'Print Router URL is not available'

I can print from a web page on my mobile no problem. I can even add the printer from the manage printer settings menu when I click there printer icon.

I am using the url and have 'enable client printing' box checked in client printing on the Administrative Setup.

What else can I do to get working?

I know I can do it all from Safari on my iPhone but it would be nice to use your app.!
