It does exactly what it is supposed to. Coverts the FBA labels to 4x6.
Creates a separate label for the carrier label and the FBA label.
Easy to use. Drag the file, click the button, done.
Worked with my Zebra thermal printer.
None so far.
I don't know why Amazon does not have built in support for a label printer with their FBA shipping labels. I don't have the patience to copy/paste labels to the printer, and cutting and taping labels is also time consuming. Found this program from a recommendation on a forum and gave it a whirl. Best 5 bucks you'll ever spend if you do any volume with FBA.
