I use Ebay post labels and the best I have been able to do is 2 per page. I changed my "thingy" (sorry very technical term) to Landscape. Then always elect to print only page 1 then; 

Print the first label.

Then, Take the page turn it around so the the first printed label is visible and sitting at the top, and the rest of the blank page is now first through the printer.  

Print second label.

Prints out slightly larger than on "Portrait" but this is the best I have been able to do until Ebay gets its act together to fix one of those tiny little things that are so annoying. I have a huge pile of scrap paper that am currently using from my previous attempts, but now at least am not adding to it! Hope this helps a little.
