This plugin lacks multisite support

Hello.

Just wanted to let you guys know that this plugin lacks multisite support. Fortunately it shouldn’t require much to make it multisite-compatible. For example most AJAX calls are not working in a multisite environment because multisite uses different URL for each site, but most references to AJAX use the default site URL. So if your network has a site with a URL https://example.com/ee/ then AJAX calls are directed to https://example.com/. This will be a problem if you don’t have the plugin enabled AND configured on your master site. For example this bug effects the “Print labels” and “Print manifest” buttons.

Just thought I’d let you guys know. Would be nice to get multisite support in future updates. Thank you for your attention.
