Troubleshooting Your Dymo 450 Label Printer

If you are having trouble getting your labels to print, start here.

Important to Note:  You may be able to print your labels from the Dymo Label software, but not be able to print them from Faith Teams.  This does not mean Faith Teams doesn’t work.  It means your software is not setup or configured properly on the computer.  Take a look at the steps below, and take note to make sure the web service is installed and running correctly.  We cannot troubleshoot issues on your printer installation.

Here are the basic guidelines to get setup:

  • Get a printer:  Supported Printer – DYMO LabelWriter 450 Turbo Thermal Label Printer
  • Get your labels: Supported Labels – Dymo Compatible 30256 REMOVABLE Adhesive – 2-5/16″ x 4″ Shipping Labels
  • Download and install Latest DYMO Drivers for your system – label printing requires a PC or Mac with drivers installed
  • Run an environment check to make sure your system is ready

The environment check should show “true” for each check.  If not, you have an issue with how your printer and/or Dymo software is installed or its status.

How can I tell if I have DYMO Label Web Service installed?

The DYMO Label Web Service is installed as long as you have installed DYMO Label Software 8.5.3 or newer using the express “Express” mode.

If you choose to install DYMO Label Software in “Custom” mode, be sure to select the DYMO Label Web Service component as follows:

If installed, there will be an executable file named DYMO.DLS.Printing.Host.exe within the DLS working folder (normally found within the C:\Program Files (x86)\DYMO\DYMO Label Software folder on Windows and the /Library/Frameworks/DYMO/SDK folder on Mac).

How can I tell if the DYMO Label Web Service is running?

You should see the DLS application icon within the system tray.  Right-click this icon to display a context menu.  The menu displays the web service’s status (i.e., “Started on port 41951” or “Stopped”).

The following shows what it looks like on Windows.

On Mac, the DLS application icon and context menu will appear within the system tray like this:

I do not see it in the system tray.  How can I start it?

Windows

You can start the web service again by navigating to the DLS working folder and running the executable named DYMO.DLS.Printing.Host.exe.

Mac

Open a Finder window, navigate to the /Library/Frameworks/DYMO/SDK/ folder, and click on the DYMO.DLS.Printing.Host.app icon.

Open a terminal prompt and enter the following command:

launchctl start com.dymo.dls.webservice

How can I start or stop the DYMO Label Web Service?

You can start or stop the web service at any time by open right clicking on the service’s icon in the system tray and choosing the Start service and Stop service menu items, respectively.  Although API functions will not execute after stopping the service, the service icon will remain in the system tray after stopping it.
