Research direction
Start by reproducing the reported output with the shown Printer construction and .text("привет андрей ❤️") call, comparing UTF8 and 860 encoding. Trace how the printer driver encodes text before sending it to the device. Done means Cyrillic letters and the smiley produce defined output on the relevant ESC/POS printer, with the supported encoding documented or tested.
Written by the indexing model from the issue text.
Description
hello everyone, I tried to print a smiley face and Russian letters, nothing comes out. Does anyone have ideas?
i tried also 860, not have result.
Code:
const options = { encoding: "UTF8" };
const printer = new escpos.Printer(device, options);
device.open(function (error) {
printer
.size(0, 0)
.font("a")
.align("ct")
.style("b")
.text("привет андрей ❤️")
.cut()
.close();
});
