Research-based comparisons for US home shippers and small businesses—starting with what works with your devices and the labels you can buy.
For mixed devices on one Wi-Fi network: Rollo documents AirPrint plus Windows, Chromebook and Android printing, and says any brand of direct thermal gap label works.
Check first: Labels feed from behind the printer, so allow about 12 in of desk depth. Rollo's warranty is 1 year.
For envelopes and parcels up to 25 lb: DYMO publishes a ±0.2 oz tolerance below half capacity, and the scale passes weights to shipping software over USB.
Check first: 25 lb maximum and a fixed display; boxes larger than a shoebox can hide the reading.
For Rollo and other external-feed thermal printers: 500 perforated 4x6 labels in a stack that needs no holder; direct thermal, BPA-free and FSC certified per Rollo.
Check first: Fits external-feed direct thermal printers like Rollo's. It does not work in DYMO LabelWriter or Brother QL printers.
