我实际上正在构建一个应用程序,应该使用热敏打印机或类似的收据打印机打印收据。我现在使用谷歌云打印,但它需要一个谷歌帐户,我希望人们能够直接连接打印机到他们的手机和使用它。有没有办法做到这一点?有没有什么库可以帮忙?我在NPM上看了一下,但我能找到的都是与蓝牙设备通信的包,但不是特别关于打印的。谢谢你的帮忙!

看一下react-native-print。它适用于iOS和Android,按照他们的说明进行设置。下面是官方示例代码:
import RNHTMLtoPDF from 'react-native-html-to-pdf'; import RNPrint from 'react-native-print'; export default class RNPrintExample extends Component { state = { selectedPrinter: null } // @NOTE iOS Only selectPrinter = async () => { const selectedPrinter = await RNPrint.selectPrinter({ x: 100, y: 100 }) this.setState({ selectedPrinter }) } // @NOTE iOS Only silentPrint = async () => { if (!this.state.selectedPrinter) { alert('Must Select Printer First') } const jobName = await RNPrint.print({ printerURL: this.state.selectedPrinter.url, html: '<h1>Silent Print</h1>' }) } async printHTML() { await RNPrint.print({ html: '<h1>Heading 1</h1><h2>Heading 2</h2><h3>Heading 3</h3>' }) } async printPDF() { const results = await RNHTMLtoPDF.convert({ html: '<h1>Custom converted PDF Document</h1>', fileName: 'test', base64: true, }) await RNPrint.print({ filePath: results.filePath }) } async printRemotePDF() { await RNPrint.print({ filePath: 'https://graduateland.com/api/v2/users/jesper/cv' }) } customOptions = () => { return ( <View> {this.state.selectedPrinter && <View> <Text>{`Selected Printer Name: ${this.state.selectedPrinter.name}`}</Text> <Text>{`Selected Printer URI: ${this.state.selectedPrinter.url}`}</Text> </View> } <Button onPress={this.selectPrinter} title="Select Printer" /> <Button onPress={this.silentPrint} title="Silent Print" /> </View> ) } render() { return ( <View style={styles.container}> {Platform.OS === 'ios' && this.customOptions()} <Button onPress={this.printHTML} title="Print HTML" /> <Button onPress={this.printPDF} title="Print PDF" /> <Button onPress={this.printRemotePDF} title="Print Remote PDF" /> </View> ); } }
