Before plugging in your printer, make sure you have:

Step 2: Install the software

2. Open the .dmg file and drag to the DYMO app into your Applications folder.

3. Approve any prompts in System Setting > Privacy & Security.

4. Connect your USB cable when prompted.

Step 3: Connect your LabelWriter printer

To connect the power:

1. Plug the power cord into the power adapter.

2. Plug the power adapter into the power connector on the bottom of the printer.

3. Plug the other end of the power cord into a power outlet.

4. Plug the USB cable into the USB port on your computer.

5. Insert the power and USB cables through the cable channel and set the printer down.

6. When the software is completely installed, connect the other end of the USB cable to an available USB port on your computer.
