The MUNBYN RealWriter 403B aims squarely at solo sellers and small shops that want fast setup, low ongoing costs, and the freedom to use generic direct-thermal labels. The DYMO LabelWriter 5XL is a polished desktop unit known for sharp 300-dpi output and smooth software workflows, but it requires DYMO-brand labels due to its Automatic Label Recognition system.
Both printers are quick—MUNBYN’s testing cites roughly 72 labels/min at 203 dpi, while Zebra rates the ZD421 platform up to 6 ips (≈152 mm/s) with the ZD421d offering 203-dpi standard and a 300-dpi option on some variants. The right pick depends less on raw speed and more on how you print
