The following printers work in plain text mode using an Arduino Giga R1 WiFi. They do not work on Arduino Uno R4 WiFi. I would not recommend buying these printers since newer printers can print on sticker paper. There is no app since the printer is intended to be connected to a cash register or a credit card terminal.
Printers ZJ-5807DD and IMP027B-BK appear identical except for the model numbers. Both advertise the name "BlueTooth Printer". Currently using printer type MPT2. Printing plain text works fine using tpSetFont and tpPrint. Graphics printing is not working but I am still looking at this.
The number of changes to support Giga/Uno R4 are very small since nano33ble, Giga, and Uno R4 use the same ArduinoBLE library. BTW, there is a beta version of ArduinoBLE for Uno R4.
