Recommendations for label printers?

[JasonGraham]

I would like to print info labels for spools, and the 40x30mm labels generated by 3dfilamentprofiles.com seem pretty much ideal.

So I ordered a Niimbot B21 from Amazon (yes, I know, RFID DRM) and… oh my goodness, it is awful. I mean, the hardware is fine, I guess. It’s the apps. The iPhone apps are shambolic disasters, and it doesn’t work with a Mac via USB or Bluetooth. Nor do I want to buy a Windows machine for this little thing, that’s ridiculous beyond reason. It’s going right back to Amazon.

Do you use a label printer for this kind of thing? What do you use? Would you recommend it?

Thanks for any ideas!

I had a similar issue a while back, and what worked for me was double-checking my firewall rules—UDP ports especially were messing things up. Also, I was running an epson colorworks printer on the same network, and oddly enough, it was causing some weird IP conflicts until I locked down static IPs for both devices. Might be worth checking your DHCP assignments too.
