用Java编写一个打印标签客户端
点击运行启动会打开首页
可以点击预览打印
点击打印可测试成功
打印机结果
前端用的是thymeleaf

}页面上预览图片和真实打印机打出来的不一致是正常的因为这是测试打印（测试本地电脑是否符合使用打印机客户端调用bartender进行打印）文章来源地址https://www.toymoban.com/news/detail-613381.html
到了这里，关于JAVA调用Bartender进行标签打印（可本地用打印机客户端进行测试打印，【云上的项目】可通过WebSocket进行通讯进行打印）的文章就介绍完了。如果您还想了解更多内容，请在右上角搜索TOY模板网以前的文章或继续浏览下面的相关文章，希望大家以后多多支持TOY模板网！
