The Dymo LabelWriter 450 is one of the most widely used label printers in the world. But installing it can sometimes raise questions. In this guide, you'll learn step by step how to install the Dymo LabelWriter 450, including the software, drivers, and your first print.
What do you need?
Before you start installing, check that you have these items on hand:
- The Dymo LabelWriter 450
- Compatible labels (e.g. 99010, 99012, or 11352)
- The supplied USB cable
- A computer (Windows or Mac)
- Internet connection to download the software
Step 1: download software for the Dymo LabelWriter 450
Installation starts with the right software. The old CDs are now outdated; you can simply download the latest version from the Dymo website.
Choose the right version for your operating system:
- Windows 10 or 11 → Dymo Connect
-
macOS (latest versions) → Dymo Connect for Desktop
Note: Are you using an older version of Windows? Then Dymo Label Software v8.7.5 is often more stable for the LabelWriter 450.
Step 2: connect and install
-
Do not connect the Dymo LabelWriter 450 yet
-
First install the software you just downloaded
-
Follow the installation instructions on your screen
-
Only connect the printer via USB when prompted
-
The computer will automatically recognize the device and complete the installation
Ready? Now you can start printing your labels!
Step 3: test your first label
Open the Dymo Connect or Dymo Label Software program and print a test label:
-
Load a roll of labels (e.g. Dymo 11352)
-
Open a standard template or create your own design
-
Click “Print”
-
Check whether the printer prints neatly and centered
Printing at an angle or incorrectly? Check whether the label is properly seated in the holder and the size is correct.

Frequently asked questions
Do I need to install the Dymo LabelWriter 450 before connecting it?
Yes. Always install the software first (such as Dymo Connect or Dymo Label Software) before connecting the USB cable. This prevents error messages or the printer from not being recognized.
My Dymo LabelWriter 450 isn't recognized. What now?
Check whether you connected the printer only after installing the software. Try a different USB port or restart your computer. Still not working? Reinstall the software and try a different cable.
What is the difference between the Dymo LabelWriter 450 and the 5XL?
The 450 is more compact and is especially suitable for smaller labels. The 5XL supports larger shipping labels (100x150 mm) and has better integrations with e-commerce platforms. Also read our blog about the difference between the Dymo 4XL and 5XL for more information.
