Printing Bulk Ebay Labels via Dymo LabelWriter 450

I am running a Dymo Labelwriter 450. I am trying to print bulk shipping labels via Ebay. I have my settings set up correctly, I have no issues printing single labels via ebay but if I do bulk shipping, then the labels pop up into adobe acrobat to print. They are formatted correctly but when I hit print, it doesn't communicate to the printer. Dymo cant help and thinks its an adobe issue.
