How to use the babel-relay-plugin/lib/RelayQLPrinter function in babel-relay-plugin

function templateStringTag(quasis, ...expressions) {
    const processedTemplateLiteral = processTemplateLiteral(quasis, expressions, 'queryName');

    const processedTemplateText = transformer.processTemplateText(processedTemplateLiteral.templateText, {
      documentName: 'queryName',
      propName: 'propName'
    });

    const definition = transformer.processDocumentText(processedTemplateText, {
      documentName: 'queryName',
      propName: 'propName',
      fragmentLocationID: generateHash(JSON.stringify(processedTemplateText)).substring(0, 12)
    });

    const options = {};
    const Printer = RelayQLPrinter(t, options);

    modifyPrinterClass(Printer);

    const printed = new Printer('wtf??', {})
      .print(definition, []);

    return printed;
  }
