Question

因此Im为我的Andorid手机制作了一个POS打印解决方案，以便可以打印到蓝牙打印机。使evreything正常工作，但是希望它在页面加载时自动打印，而不必单击我制作的打印按钮。

所以我的“打印按钮”可以正常工作。如果我在Android上使用FireFox，则在页面自动加载时可以打印，但可以，但是如果我使用Chrome，则它不会在加载时启动该功能，我不知道为什么。

Answer 1

在Chrome浏览器或某些其他Android浏览器（如Samsung Internet）中将无法使用。这是一项安全功能，可保护用户免受垃圾邮件的侵害。如果不单击按钮，您将无法实现。我希望这对您来说不是一个大问题，但这是不可能的。

Chrome On Adroid OS出现问题，但功能未在加载时运行
