New Barcoding Process

Hi

I still need to figure a way to print my barcodes but i am first wondering if i can change the names of the products that are on the barcodes currently? I want to make it easier to put new stock in and have a broad name for the products.

Also if anyone has figured out how to get a munbyn shipping label printer to print tiny barcodes please please please let me know because mine dont scan and im at my wits end!

Thanks
