I saw this video the other day on this cool cheap little thermal printer on temu and AliExpress
A few comments after using it a couple times.
It's super easy and fast and of course cheap! Only problem is you have to install a proprietary software on your phone. My recommendation, use a dummy Android phone just in case!
I ended up paying 16 euro for the printer and five rolls of paper which will cover me for forever.
Fun Little Gadget, worth every penny :)
