QLN320 connecting to Cold Fusion app in the cloud

I just purchased a QLN320 and am trying to configure it to print labels from a Cold Fusion application in the cloud. I'm not sure the easiest way to do this. One thought I had was to have Cold Fusion send an email and have the QLN320 download the email and print it that way, but in my tests I haven't been able to get it to work. Are there any good diagnostics to see why this isn't working? Am I way off base in using this approach? Any help would be appreciated. Thanks. -Dave
