My customer would like a mobile printing solution for creating shelf labels. I am brand new to Square. Any suggestions for getting started?
Currently we don’t have any APIs or SDKs that print labels. You can definitely pull information from our APIs to your service that prints the labels on 3rd party printers. We’re constantly working to improve our features based on feedback like this, so I’ll be sure to share your request to the API product team. 
I would like to second this feature request. For myself if i could push price labels on a pr8ce change automatically either api or dashboard
Thanks for sharing. It helps me a lot.
