Frequently Asked Questions

Q: What interface options does this 58mm embedded thermal printer support?

A: This mini thermal printer offers three interface combinations: RS232 + USB, TTL + USB, or RS232 + TTL. You can choose the option that best matches your hardware setup when ordering, making it highly versatile for POS, kiosk, and embedded system integration.

Q: What type of paper does this thermal printer use?

A: It uses standard 58mm (57.5 ± 0.5mm) wide thermal paper rolls with a maximum roll diameter of 40mm. No ink cartridges or ribbons are required — the thermal printing method uses heat to create text and images directly on the paper.

Q: Is this thermal printer compatible with Raspberry Pi, Arduino, or Linux systems?

A: Yes! The INSTOFC mini embedded thermal printer is compatible with Windows, iOS, Linux, and Android platforms. Its TTL interface option makes it especially well-suited for integration with microcontrollers like Arduino and single-board computers like Raspberry Pi.

Q: What power supply does this printer require?

A: The printer operates on DC 5V–9V, which makes it practical for embedded and portable applications. It does not include a battery — an external DC power adapter or regulated supply within the specified voltage range is required.
