Hi, I've written the CUPS driver to use the M02 printer with linux: https://github.com/vivier/phomemo-tools I'm not able to use the GUI to connect the printer, but once it is done manually it works fine. I've also defined label formats to use with glabel. I don't know if it will work with M02 PRO, but at least the line size needed to be changed (203 dpi -> 300 dpi)
