So I've completely updated my review after talking with a Guru and having them inform me of a feature I wasn't aware of...
I hope this review helps you and serves as a better instruction manual than what is available in the Knowledge Base.
Scenario: We want to add asset/price tags with bar codes to all of our merch so we can implement asset tracking and use barcodes at checkout.
First install the Barcode Printer software from the app store.
1) You need to buy a supported Dymo printer. We bought a LabelWriter 450 Turbo off Amazon and it works great. FOLLOW INSTRUCTIONS to install Dymo software on your computer, then connect the printer.
2) Make sure you buy SUPPORTED labels We are using the Dymo 30336 for asset tagging. They are 1" tall by 2 1/8" wide and fit perfectly on our existing price tags. We are putting item name, price, size and the barcode on each label.
3) Go into Barcode Printer software and make sure you assign barcodes to all of your existing inventory by pushing the button in the top right corner. Choose the option to assign to everything that doesn't already have a barcode. You'll need to do this step EVERY time you add new items to make sure they get a barcode auto assigned.
4) Go to the Barcode Design button in the Barcode Printer app. Choose the layout that matches the supported label type you want to use. Click the check-box options to choose what data will be printed on your label.
5) IMPORTANT: This is the part that the Guru helped me with. If you want to print a label for an item, go into products and open the product. Next, choose "More Options", then scroll down to the "Print Barcode" option. From the next screen, you can choose which items (variants) and quantity of barcodes you'd like to print.
6) DO NOT attempt to use the "Export to Barcode" option from the main product page. If you select a bunch of items and use that feature, you can export to a CSV file and then import into the Dymo application directly. I tried this and wasted $10 in labels printing garbage. Why garbage? Because it doesn't actually print labels for your inventory. It prints your PRODUCT list. For example, if you have a clothing item in small, medium and large, it will print three labels no matter what your inventory count is for that item. If you have zero smalls in stock, 10 mediums and 5 smalls, you'll just get three labels. Small, Medium, Large. The "Export to Barcode" feature is worthless...it should be on the Inventory page, not the Product page.
