Star Micronics SM-T300i
Rugged three-inch mobile receipt printing for field service, delivery, public safety, transportation, and other work away from the counter.
The Star Micronics SM-T300i pairs Bluetooth 2.1 + EDR and RS-232C serial connectivity with an IP54-rated enclosure for supported iOS, Android, Windows, and macOS workflows. It prints 80 mm direct-thermal receipts at up to 75 mm per second and supports both StarPRNT and ESC/POS emulation.
Both current U.S. configurations include a charger. Choose the standard model without a magnetic-stripe reader or the MSR-equipped model for applications that need three-track card reading and 3DES encryption.
