CSN-A2 Thermal Printer — Kashino / Cashino — CSN-A2

Availability

In stock

Mini panel-mount direct-thermal receipt printer for 58 mm paper (48 mm print width), 8 dots/mm, ~50–80 mm/s. Available in TTL, RS232, USB, and parallel variants; supports ESC/POS text, barcodes, QR codes, and bitmaps.

Logical pinout · physical placement not verified

VH
Printer power input on POWER-side pin 3. Supports 5-9V; faster/cleaner printing at higher voltage. Always source from a dedicated supply rated for ~1.5-2A peaks — never the MCU's regulator.
Type · PowerVoltage · 5V
GND
Common ground. Connect both POWER-side pin 1 and TTL-side pin 4 to the MCU/supply ground rail.
Type · Ground
RX
Printer UART RX on TTL-side pin 5. Connect to an MCU TX GPIO. Default baud 19200; the printer's self-test slip prints the actual configured baud.
Type · UART
TX
Printer UART TX on TTL-side pin 6. Optional — only needed if you want to read printer status back. Note: the CSN-A2's TX line is 5V; do NOT connect it directly to a 3.3V MCU RX without a level shifter or resistor divider.
