cannot print on D110_M

[jonsnow1357]

Hello,

I just got a new D110 Niimbot (says D110_M on the case) and all I can get so far are empty labels :(
I am trying to print png images from CLI.

There is a crash at line 296 in NiimPrintX/nimmy/printer.py because the return packet has 8 bytes instead of 4
I would be willing to help debug further but I cannot find any details about the BT protocol used to decode these packets.

Please advise

Just ignore the extra data.

Alternative implementation

AndBondStyle/niimprint#38

I tried, and it prints 2 empty labels ...

I think this is a different protocol. I have added some debug prints in the info section and you can see the differences.

• SN is ASCII and not hex
• SW ver is 4.17 in the Android app
• HW ver si 4.01 in the Android app

Would you be willing to add support for this?
It's not clear to me how you can add multiple protocols to your code ...

That's not my code, and I am not the NiimPrintX author 😄

I think @LorisPolenz implemented support for your printer in #6
As I know, D110_M is compatible with B1 print task. But this PR is not accepted as this project is not maintained.

Alternatively, you can try niimblue, which is supported by me 🙂

I can confirm that #6 works for D100_M.

Thank you

I created a fork that supports D110_M out of the box with some sane defaults (correct default rotation for GUI, D110_M label configuration etc.) if anyone is interested.

@Eamo5 Prebuilt binaries would be a good thing.
