I had some problems with D11_H printer - it didn't print anything - just empty labels. I changed the command: start print to the line ( 2 bytes of data in place of one)
await self.send_command(RequestCodeEnum.START_PRINT, b"\0x00\x01")
The printer parameters:
Software Version : 10.32
Hardware Version : 10.25

Thats interesting. Is this represents amount of "pages" to print? Seen this referred as v4 in similar project which packs number of pages to print in 2 byte big endian (+ some additional data).

I have tried to apply the patch and for me this gives empty labels:

@corpix If I'm not mistaken, D11_H uses 7-data-bytes PrintStart packet, not 1 or 2.

Thanks to your fix, it now works like a charm with my D11_H ! This should be committed to main.
Thanks to good-guy-coder for bring this to us at first place.
Even if NiimBlue is now doing quite a good job, It would be cool to have a standalone executable.
Thanks for your efforts guys
