Reddit mentions of 4 Rolls - 30252 Dymo Compatible Address Shipping Labels for DYMO LabelWriters 330 400 450 Twin Turbo Duo 4XL Printer

I have a DYMO 450 turbo also and I mainly use 30334 size labels. Both Amazon and Inventory Lab will print this size.

>I've seen a lot of people basically taking snapshots on every label from a 30sheet which seems kind of wonky.

If you want to use the Dymo with Amazon directly you need to use Amazon's Scan & Label page. Inventory > Manage FBA Shipments, then near the top of the page look for Scan & Label

It prints out labels for one SKU at a time.

Since Chrome changed, it's a little more difficult but you pick the product you need a label for by scanning it or entering your SKU. Then you can either print it or save it. If you print, the chrome print window opens and you need to play with settings to make sure the label fits.

1. Select the Dymo printer
   
2. More Settings > select paper size. 30334 if you are using that size. If you don't see it, you need to print using system dialog
   
3. No margins.
   
   You only need to do this for the first label.
   
   
   
   Inventory Lab is a lot easier. You run the printer setup under account settings to choose your label size. Then you choose if you want the label to print automatically when you list an item, or only when you click the print button.
   
   
   
   Keep in mind, you are suppose to use removable labels when applying directly to the products. That said, Amazon doesn't follow their own rule here and I've learned that the longer removable labels are on, the less removable they are.
   
   I've used a few label brands.
   
   

• Best quality is the DYMO brand but they are absurdly expensive.
  
• For permanent labels, I'm using https://www.amazon.com/gp/product/B00IC8B5VA right now but I also have https://www.amazon.com/gp/product/B00JPPLU32 sitting on the shelf. Both seem to work fine.
  
• For removable labels I use https://www.amazon.com/gp/product/B00CBAPJ30
  
• I also have some 3.5 x 1.125 labels I rarely use on some specific larger items https://www.amazon.com/gp/product/B001AVNLHC

  As far as printers: I use the Dymo 450 turbo and brother laser https://www.amazon.com/gp/product/B00LZS5EEI/
  
  I use the laser printer for shipping labels mostly but sometimes for product labels if I'm sending like 80 of the same thing.
  
  I spent a lot of time when I started, trying to decide what printer to get. I started with the laser because: 1. I can use it as a regular printer for non-fba stuff, 2. It will print both fnsku and shipping labels, 3. It is really inexpensive.
  
  I added the DYmo later because: 1. I hated all the wasted labels if I wasn't printing a full sheet, 2. I do RA and matching labels from a sheet with 30+ different products is time-consuming, 3. I often need 1 or 2 labels and it was difficult to do on the laser.
  
  I haven't looked in awhile but my dream printer would be a thermal transfer printer that is large enough to print shipping labels as well as fnsku. I just can't justify spending $500 on it.
