I didn't think you can create shipping labels that don't have an associated transaction in MultiOrder Shipping? Also, I use that link above nearly every day and I've never had problems, except if PayPal is down.
I best double check to be sure now that you mention it , brb, ok it is a virtual brb huh since i have not posted yet but just pretend your waiting ,virtually ,lol, tick tock tick tock,,,,
Just finished and no you do not need a paypal related transaction to print a shipping label ,whew ya had me thinking i was mixed up ,again ,i do that on occasion.
