Marc Lazar of CellarAdvisors has been working with dozens of clients since early 2005 to get them all inventoried and barcoded on CellarTracker. Based on feedback from some clients (David Pedowitz), Marc came up with the idea for a specially perforated label (with a more lightly glued portion), and I worked with him to add a 'removable' barcode to fit these labels. That way you can easily tear off and save a copy of the barcode for later scanning and removal. These work with all Dymo LabelWriter series printers, including 300, 330, 400, 450, Duo and Twin Turbo models. The original version of these labels was a non-standard size. As of July, 2010 we have moved to a standard Dymo size. The newer labels have yellow glue on the back of the tear-off tab. You need to choose the correct label size in your label settings.
Here is a printed label:
Here is a label after it has been torn at the perforation:
