reset method
Clear the buffer and reset text styles.
Sends ESC @ to initialize the printer, which returns it to standard (continuous) mode — the default for roll paper printers. ESC @ already cancels page mode on compliant printers.
Implementation
List<int> reset() {
List<int> bytes = [];
bytes += cInit.codeUnits; // ESC @ — initialize / cancel page mode
_styles = PosStyles();
bytes += setGlobalCodeTable(_codeTable);
bytes += setGlobalFont(_font);
return bytes;
}
