Your lib is so nice, its work with the most POS printers, congrats.
We used for a lot projects.
Ive a new issue with a SUNMI device, as i read some other customers has.
Ofc first of all, i have read the issues here.
Most of them called an "r" problem: #509 #471 #317
Plus one, there is a tip: #204
Ive tested the suggested solution, its not working.
Below ive attached some photos about the test.
Some remark:
On a full size receipt u see the "r" symbols. Its mostly at the line start and at the end. But if u look a little closer, u notice the field/column style blocks open and close tags marked by "r" char.
If i changed the encodings the qr and barcode is printed perfect, but the texts are empty.
This confirms that there is a problem with the char encoding. (cuz empty)
But! from the pdf-s only working with 15 and 16 encodings (15 "CP928"; 16 "Windows-1252";) otherwise texts are empty.
A lot times in the issues u asked the guys its the printer support ESCPOS, the answer is yes, on the pictures the qr barcode and other infomations are corrent. Only the open and close tags has a bug, or something else. https://ota.cdn.sunmi.com/DOC/resource/re_en/ESC-POS%20Command%20set.docx
Plus one more information, ive installed a RawBT application from Play store and printed a some ESCPOS examples.
Do you have any ides, how to solve this problem?

So, first plan was change the encoding. The lib built in encoding prints not working, but this info is online in two different docs.
