★★★★★ 5
20 X 40mm vial labels
Size: 1.6“ X 0.8"-White, Color: White
Works perfectly. Make sure when you’re buying labels that you don’t buy M1/M2 labels unless you have the M1/M2. You need direct transfer unless you have the M series with the fancy color cartridges etc. The “fancy” labels won’t work on normal thermal printers, they need the color cartridges to show up.
Anyway this is the 20mm X 40mm size. Perfect for vials. Works in many other non-branded machines.
