The [Adafruit printer starter pack](https://www.adafruit.com/product/600) can also be a convenient option to get started, as it includes all the necessary components for printing (except the conversion cable). To ensure proper functionality, enable the printer driver in the [Krux settings](./getting-started/settings.md/#thermal), set the Tx pin and baud rate value to either 19200 or 9600 (depends on the printer), as explained in this [Adafruit printer tutorial](https://learn.adafruit.com/mini-thermal-receipt-printer/first-test). You will need to connect the device's Tx to the printer's Rx and device's ground to the printer's ground, do not connect any other pins because a wrong connection may damage your device. The printer requires a dedicated power supply, typically with an output of 5 to 9V (or 12V) and capable of supplying at least 2A. For more information, [see this discussion](https://github.com/selfcustody/krux/discussions/312). +Many TTL serial thermal printers may be compatible, but currently, the [Goojprt QR203](https://www.aliexpress.com/w/wholesale-Goojprt-QR203.html) has the best support (except this printer only supports ASCII or Chinese characters, non-ASCII characters will be printed as Chinese).

Check your device and printer model connection first, Yahboom comes with PH2.0 4Pin female connector; Dock and Bit doesn't have a connector. For a more reliable connection, it is recommended to cut and solder the wires of your custom cables instead of using jumpers. \ No newline at end of file
