If you are meaning Ebay postage labels, we have found an easy way to print 2 labels per page. 

1 Go to Print Ebay label and get it ready to print.

2 Before you hit Print, change option to Landscape (not Portrait). This turns the label on its side.

3 Put the sheet of A4 in the printer just like normal and press print.

4 Once the first label is printed, take the sheet and turn it around, with the printed label facing up at the top end and the sheet of paper now has its blank end inside the printer.

5 Now do your next label, and voila! 2 labels per page.

I know this is not as economical as some other options suggested but is a very easy way to print labels and for me who is a complete clutz and nana on the computer this was the easiest. Also don't feel quite such a paper bandit.
