To rename your printer or to add/change tags, you will need to go to Ebriza POS.
From there, at the Meniu and select: Printers
A new window will open with all the printers that you have installed on your location.
Click on the Printer you want to rename.
From here you can rename your printer or add/change tags. Don't forget to Save.
If you have multiple tags, these ones will be separated by comma.
