I messed around for an hour with paypal and had to void two labels---FINALLY i just printed it from USPS.com ---which i could only print Priority Mail labels--ugh. It was worth the extra $$ for the hassle!
I printed one label from Etsy, but I have another order from another website that needs to be printed from paypal, but no matter what I am doing it isn't working. So it isn't an Etsy problem. :( Thanks for all of the replies though!
