FAQ: Is there an SDK for Dymo Postal/Shipping Scales?


Q) Is there an SDK for the Dymo M5 Digital Mailing Scale please. We need to capture the weight into an application to print the labels.

There are no drivers or SDK as such, but the scales do adhere to the HID standard so you should be able to access them that way.

The HID standard is documented here. Weighing devices are covered in section 4.

Jan Axelson has a great page on HID development with lots of examples and links to resources. I recommend this as a starting point.

There are many other examples of HID Scale development online, such as Nicholas Piasecki’s page and Mike Obrien’s libraries.

Note: This will not work for the M1 and M2 scales, as they are "stand-alone" and do not have a USB connection.
