label

label prints text labels on the Brother PT-P710BT over USB or Bluetooth.

Installation

go install crdx.org/label/cmd/label@latest

Usage

Usage:
    label [options] print <text>
    label [options] status

The printer is auto-detected: USB is tried first, then Bluetooth. Note that Bluetooth is only supported on Linux.

The default font is Spleen for its aesthetics when printed on the PT-P710BT, but this is subject to change.

USB permissions

Raw USB access requires permission to open the device node. Either run it as root, or add a udev rule:

echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="04f9", ATTRS{idProduct}=="20af", TAG+="uaccess"' \
    | sudo tee /etc/udev/rules.d/70-ptouch.rules
sudo udevadm control --reload

Then disconnect and reconnect the printer.

Bluetooth

Bluetooth uses Linux RFCOMM sockets and BlueZ, so it is only supported on Linux.

Pair the printer once with bluetoothctl (use PIN 0000 if prompted):

[bluetooth]# scan on
[bluetooth]# pair A4:C1:38:AB:CD:EF
[bluetooth]# trust A4:C1:38:AB:CD:EF
