This article assumes you have already gone through the steps to install the printer drivers. Please see this article for more details on these steps.
If the printer isn't working properly, try the following steps. If all else fails, go through a clean install. If you are still having issues, please reach out to support.
By default, events do not print labels. Confirm that you've set at least one label to print and the person checking in matches the criteria. To set labels, visit the Attendance > Settings tab of the event and review the Check-In Labels section.
Also, make sure to choose the label that corresponds to the printer you have connected to the check-in station.
If using Dymo
Confirm the correct product was installed. You should either have Dymo Connect or Dymo Label Software installed depending on your printer model and operating system (not both). Review this article and make sure the correct version of Dymo is installed. If you installed the wrong one or installed both, then uninstall all Dymo products and follow the instructions in that article.
Restart computer after installation and see if you are able to print labels now.
If the correct version is installed, make sure the Dymo web services are running. Check the system tray on Windows or top menu bar on MacOS for the Dymo web services. See this article for screenshots of where these are located.
If using Zebra
Confirm you have QZ Tray installed and running. This is required to print using Zebra. Follow the instructions in this article for information on installing and setting up Zebra correctly (including setting the printer name).
Set as Default Printer
The printer may create a new instance whenever you change the USB port you use when connecting the printer. This may cause issues with printing as the new instance may not use the correct drivers. If possible use the same USB port when connecting the printer to the check-in station to avoid this issue.
To check if you have multiple printer instances, go to Devices and Printers in the Control Panel (Windows) or System Preferences (Mac). Set the printer you use as the default one.
If you have multiple of the same label printer installed, you should remove the inactive ones.
To refresh the printer, unplug the power cord from the printer for a full 30 seconds, and then plug it back in. When you plug it back in, make sure the connection is secure. If it feels loose, that could cause connection problems and you might need a new printer/cable.
If the previous sections did not help, it's recommended to uninstall and reinstall the printer drivers again. Remove the printer from the printers area of your computer and unplug the printer. Then follow the "Install the Printer" section of this article to make sure you've installed the printers correctly.
