How to Change Order Status Programmatically in Magento 2

The Magento 2 orders have an order status that is linked with a state in the order processing flow.

One can create custom order status in Magento 2 if required.

For example, a custom order status “printed”. When the admin prints out the packing slip, the order status is changed to “printed”.

Instead of doing it manually, one can change order status programmatically in Magento 2.
