I just bought a Phomemo D30 thermal label printer to label my electronics component boxes last week, and I was wondering if I can hack things to send it images from my PC instead of the phone app it comes with.

I found this repo, but I don't know if that's compatible with the D30 (the chassis pictured is of a different printer): https://github.com/vivier/phomemo-tools

Someone in Issues asked the same question, but the author wasn't able to answer for lack of hardware. I guess I need to try and/or contribute!

The "Print master" phone app is uploaded under a different brand name (QUIN LLC), and other brands also seem to sell a D30 printer. I didn't really do the work of finding out where these truly come from. Perhaps someone's got a repo up under a different name.

I've done 0 comparisons to other models in practice, but FWIW it does what I wanted it to do very well. All my stuff is obsessively well-labeled now. In fact, I labeled the printer in a mad-with-power move ... https://eikehein.com/stuff/label_printer.png
