setGlobalFont method
Set global font which will be used instead of the default printer's font (even after resetting)
Implementation
List<int> setGlobalFont(PosFontType? font, {int? maxCharsPerLine}) {
List<int> bytes = [];
_font = font;
if (font != null) {
_maxCharsPerLine = maxCharsPerLine ?? _getMaxCharsPerLine(font);
bytes += font == PosFontType.fontB ? cFontB.codeUnits : cFontA.codeUnits;
_styles = _styles.copyWith(fontType: font);
}
return bytes;
}
