WHYTE QUARTZ review for Retail Barcode Labels

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!
