When you load in a new direct thermal label, there are two actions that need to take place:
1) Run the automatic label identification on the printer.
2) Set proper label settings on your computer.
3)Run the automatic label identification.

2) Set your custom label size
①For Mac:
Select or input label width and height that matches label size installed in printer in prompt window.

②For Win:
Go to "Control panel" -> "Devices and Printers"
(Right click on "This PC", choose "Properties", then click on "Control panel"-> "Devices and Printers")

->Right click on "Label Printer" -> choose "Printer Preferences"

-> Go to "Page Setup" -> Select the paper type in "Name"

If there is no label size you need, you can click "New" to create a label size.
Change Paper name and input width and height, click "OK"

Third step：
The application you are using (e.g. Adobe Reader) could be over-riding your driver label setting and sending the print in a larger / smaller size to the printer. Look for "Page Setup" or "Paper Size" in the print prompt and ensure it is set to the size you want.
