Note: The easiest setup would be to connect your Etsy Store to the Rollo Ship.
To update your Etsy settings to generate 4 x 6 shipping labels:
Only USPS shipping labels can be formatted for 4 x 6 label printers.
- Sign in to Etsy.com.
- Click the Your Account icon, then click Shop Manager.
- Click Settings.
- Click Shipping settings.
- Click Shipping Label Options.
- Select Format my labels for 4x6 Label printers.
Please note that after you change the label format to 4 x 6, only new labels will be generated correctly. To avoid this problem, delete previously generated labels and create new ones.
