Open One of the links first, and log in before opening any additional pages.
You will need to let it load, it will usually not show up properly (All the SKUs in one bar). Close, and re-load it.
You will need to click Manual Input, then "Invue Accessory Tag" BEFORE clicking "Refresh Tag".
To avoid shadowing on Accessory tags (Where some of it prints previous tags onto other tags), do 6 tags on one side, flip the page, and print 6 on the other side.
Tags are arranged based on Number on Plan-o-gram.
