So eBay, in all there infinite wisdom just did an update and of course screwed up something else. Basically, they made bulk printing disappear. I figured out a work around and hopefully it can help a few people who print more than a few a day.
1. Go to your seller hub and click under tasks on the "Print labels and ship" link(you can't click on notifications to get into bulk shipping label anymore, they broke that link, for now)
2. Once you see all your items awaiting shipment select them all with the select all radio button and then click shipping from the drop down, select "purchase shipping label" from there you will be put into the bulk shipping area like days of old.
Hope this helps
