# 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
|
||||
