Brother P-touch PT-D610BT vs MUNBYN RealWriter 403B
Which should you buy? Our verdict on both, pulled from our full The Best Label Printers: 4 Compared (and One to Skip) comparison.
The PT-D610BT wins because laminated TZe tape genuinely lasts and the format is stocked and cloned widely enough that the cartridge lock-in stays manageable. The RealWriter 403B is the runner-up and the cheapest to feed, because it takes ordinary four by six labels from any supplier instead of a proprietary cartridge.

Brother P-touch PT-D610BT
Buy itThe all-rounder: keyboard, Bluetooth, and laminated tape that outlives everything else here.
- Laminated TZe tape resists water, sunlight, and chemicals, so labels stay legible for years
- Works standalone with a QWERTY keyboard and colour screen, or over Bluetooth from a phone or computer
- Takes tape from very narrow up to about an inch wide, covering cable flags through shelf headers
- TZe is the most widely stocked and widely cloned label format, which keeps the lock-in survivable
- Genuine tape cartridges are expensive, and cost per label is the highest of the recommended picks
- Bulky for a handheld and happiest running on the mains adapter rather than batteries

MUNBYN RealWriter 403B
Buy itThe shipping-label pick that skips cartridges entirely and lets you buy media from anyone.
- Uses standard four by six direct thermal labels in rolls or fanfold stacks, so there is no proprietary cartridge to buy
- Bluetooth and USB, and it plays nicely with the common selling and postage platforms
- Barcodes and QR codes print sharp enough to scan first time at the carrier
- No ink, toner, or ribbon, and auto-calibration handles new label batches without fuss
- Does one job only: no keyboard, no screen, and no narrow tape for cables or jars
- Direct thermal output fades in sunlight and heat, so it is wrong for permanent asset tags
