Troubleshooting Mac OS X issues

Blocked Software Install

The Dymo Label Software and Dymo SDK are packages downloaded online and are considered as ‘third party apps’. If you are unable to install your Dymo drivers and you’re getting a message similar to this, check ‘Security & Privacy’ in System Preferences to see if your OS X installation is blocking the ability for you to install the software on your computer.

Click the padlock icon at the bottom left of the window to make a change and allow apps to be downloaded from ‘Anywhere’.

You should now be able to install the Dymo LabelWriter software and SDK. Make sure to switch this setting back to the original setting after the software has been installed.

Troubleshooting Windows issues

Blocked Software Install (Windows UAC)

Windows UAC (User Account Control) may occasionally block your ability to install programs on your system. If you have Administrator access, you can bypass this option by following this Microsoft article.

Windows 8 & IE11 in Metro Mode

There have been several churches reporting a loss of functionality for label printing when they’re using Internet Explorer in Metro Mode.

LabelWriter 450 and 450 Turbo Printers – USB 3.0 issues

Some Dymo LabelWriter 450 or 450 Turbo label printers that are manufactured after April 1st, 2014 may not install properly on Windows 7 computers when connected through a USB 3.0. If you are encountering this problem, Dymo has a software update that can fix this problem. For more information, please visit this article to see if your label printer has been affected by this.

Printer Not Found / Unknown Device

If your Dymo Printer is plugged into a USB port and the computer isn’t recognizing the printer, try these steps.

  1. Make sure the printer is turned on. Plug the USB cable into the USB port of the computer. If yo do not get a ‘New Hardware Found’ message, launch ‘Device Manager’ by going to Start > Runand searching for ‘devmgmt.msc’.

  2. In the Device Manager window, see if there are any devices marked with yellow flags. Check under Universal Serial Bus Controllers if there are any records for ‘Unknown Device’. If you have found any devices marked with either of these, perform an uninstall of the device.

  3. Unplug the USB cable from the computer and restart the computer.

  4. When the computer boots up, download and install the latest Dymo driver. Make sure the printer is turned on before plugging the USB cable back into the computer. The computer should then detect the printer and install the drivers automatically.

If you do not get a ‘New Hardware Found’ message, or no mention that a printer is listed in the Device Manager, then try this on another computer. If the second computer fails to recognize the printer (after performing the above steps), try to contact Dymo support to see what other areas to check.
