Key Points: Printing Production Tracking Labels

1. Default printer
Ensure default printer is set.

2. Testing on local system
If testing on local system, use Firefox. Chrome blocks downloads from insecure sites, which prevents labels from printing.

3. Install Ubuntu 24.04.3 (As of JAN 2026)
A bootable USB stick is needed to install Ubuntu desktop. Create with https://rufus.ie or similar.  Select not having to log in on start-up option.

Switch power save screen blank

Switch off automatic locking

5. Install chromium
Open the terminal and run:

sudo apt-get install chromium-browser

Change the site settings to allow multiple downloads without user notification

 chrome://settings/content/automaticDownloads

Login into customer site from terminal using Integrate

When asked to save, choose never. This stops the browser asking user if they want to update their password each time they scan their card.

Add the following command to start-up applications:

chromium-browser --disable-translate --disable-infobars --disable-save-password-bubble --start-fullscreen --kiosk --kiosk-printing http://<company_domain_here>/Terminal/Production/LabelPrinter

Note: Press the Windows key and start typing start application to find it.
