These do not work well with the Polono Thermal Printer that I have. Printing quality is very low no matter what I do with the settings for the printer. I have used higher-quality stickers to make sure it was not the thermal printer itself and they have been looking great.Have a Rollo thermal printer and these are quick to be scanned by the printer, yet they do not print very dark - even with the lowest speed and highest density. Am now making silly labels to burn through the rest of the roll so I can buy from another manufacturer...I have a wireless Rollo printer and when I saw these, I knew they'd be the perfect color for our new shop which features the Eddie Munson ring set worn in Stranger Things 4 - red and black - perfect! After I printed off about fifty, they started getting VERY faded and I thought maybe I needed to print fewer at a time, but when I opened my printer, the red was leaving residue that I had to scrape off with my nails. Once scraped off, they printed well again but I had to open and scrape every 25 or so labels. I'm not even sure I got it all and it affected my regular shipping labels. I will not be buying these again, it's not worth damaging a $200 printer.This product arrived on time and was exactly as described. We have 2 small businesses and we print labels for the logoes.I wasn't sure these would work with my thermal printer, or if I could do what I wanted. Glad I was wrong on both counts. These turned out great!I have an offnova thermal printer. They really need to list which printers are compatible with their labels in the description. Pretty color but unfortunately that's all I can say about them.お値段少し高めですが小さい子のシール貼り製作にはもってこいでした。ただ、ロールなので保存する際は剥がれやすいので注意が必要です。品物は良いが値段が高い
