After some messing around and googling I found out, its actually super easy to print all your listings!
First click on Active under my eBay. After your active listings come up, decide what order you want them printed in. Title will do alphabetical, price will do high-low, click again and it will do low-high, etc.
Or just print one category by clicking on "store category" and choosing the one you need to print.
(Variation - Another way to access your store categories click here and then click on the number in your category NOT the title)
Categorized by number of watchers high-low
Next find the print button, you may need to "CTRL + scroll out" here in order to see it. I couldn't find it at first because I was too zoomed in.
From there it will take you to a web-print page, which you can easily print using your favorite method.
Today I needed to print my flatware inventory because it's time to take stock. I sold someone two teaspoons that were actually serving spoons:/
Hope this helps!
