Cyrillic printing. setTypeFontB

[fobus821]

I use the GOOJPRT MPT-3 printer
Firmware: MTP-3B-YC-8008
Font: 1.10
The problem is that if you use setTypeFontB, the Cyrillic alphabet is printed incorrectly. If you use setTypeFontA or setTextNormal, everything is printed normally. Note: On firmware MTP-3B-YC-6107 and Font: 1.09, everything works fine. Is there a solution in the code? Is it necessary to flash to an older firmware?

This seems more a problem with the specific printer firmware

But still, have you tried setting Cyrillic when setting up the printer?

  let printer = new ThermalPrinter({
      type: PrinterTypes.EPSON,
      interface: `tcp://${pInfo.ip}:${pInfo.port}`,
      characterSet: CharacterSet.PC855_CYRILLIC, // or PC855_CYRILLIC2
  });
