Retail Barcode Labels

Why are you only supporting only 3 sizes of labels with the Zebra ZSB Label Printers? Zebra Barcodes ZSB-LC6 (2.25" x 1") - 57mm x 25mm
Zebra Multipurpose ZSB-LC7 (1.25" x 1.25") - 32mm x 32mm
Zebra Jewelry ZSB-LC8 (2.25" x 0.5") - 57mm x 13mm

For some reason it completly quit on me. It show me an error. so i deletd it and try toinstall it again and now the app just doesn't work. doesn't allow me to add it and it show me the error again. this is all crazy. I have no idea what to do. I have lots of labels to make and ths is very frustrated.

I thought this app and using barcodes on my products would be a super easy way to help me sell in person faster during fairs and markets, but just printing literally my very 1st page of barcodes was a disaster! I'm using avery labels and printing from my office jet printer and it doesn't print the description (why?? there's is plenty of room!) I can't print a barcode on my jewelry tags because Shopify doesn't support that label...what? Why? Makes NO sense at all since you're supporting all other avery labels! Shopify support while very nice just said-we don't support it and we don't support my printer (what? My printer works FINE and the barcodes work on the labels I've printed so far. Ugh-just frustrating! I guess you get what you pay for with a free app!
