Since I haven't found any reasonable way to use broher p-touch software on linux with Brother P-Touch P750W printer, with help of this ruby code I've written a python utility for printing labels.
Works also with Brother P-touch PT-E550W
python labelprint.py text_to_print path_to_printer [custom_datamatrix_data]
- For me the printer is located at /dev/usb/lp0 and belongs to the lp group.
- Without the last parameter, datamatrix contain text_to_print data
