I'm using this plugin for my clients to print their invoices from our site. However, since I'm using https on these invoice pages, the print buttons do not show up and I have to manually upload them and point to them in the settings. Secondly, when you click print, we're not getting the neat print pop up that allows the users to remove items they don't want.
This only happens on pages that are https, all the other pages work fine.
Any help would be greatly appreciated.
