Brother QL-500 Label Printer
- Don't !!! add the brother QL-500 with the default UI of your Ubuntu Linux 18.04 !!!
- Use
https://localhost:631/
Really! Do this! - You absolutely don't have to install the cupswrapper or lpr drivers from support.brother.com. Just use the usually preinstalled and recommended foomatic driver on your Ubuntu 18.04.
- Remove any other instance of this printer in your configuration and use only the one installed by this.
- You want to use gLabels for editing your labels. Not LibreOffice. Believe me.
- Just type
sudo apt install glabels
and enjoy simplicity.
