It is not possible to print barcode labels in Assetminder. It is possible to generate the barcode using another system such as a 3rd party barcode generator.
1. Google barcode generator
2. When the barcode generator is selected, create a barcode for the registration number
3. Click to create the barcode
4. Test the resultant barcode on the screen by scanning it with the Assetminder mobile app. If the app scans the barcode ok and finds the asset, print the barcode and apply to the asset.
