# thermatext
fancy name, QL-570 text formater
### TODO
- use as printer
- works, but cant detect the length of text, will output a set (page?) length
- fix missing font defentions
- fail to take into account letter width
- telegram bot (!)
## CLI
`sudo brother_ql -b pyusb --model QL-570 -p usb://0x04f9:0x2028/000M12345678 print -l 62 logo.png`
## python
python tries to detect letter width and maximise it to fit the label printer constraints (62mm width)
`python thermatext.py "label to print"`
## inkscape

`/home/${USER}/.config/inkscape/extensions`
symbolic link the dir fro here to the inkscape extension
