推荐答案

按打印按钮时，使用JavaScript将打印按钮的显示属性设置为隐藏。当打印页面关闭并返回主页面时，请刷新它并显示按钮。

When you press the ''print'' button, set the display property of the print button as hidden using JavaScript. When the print page is closed and you are back to main page, refresh it and show back the button.

//hide
document.getElementById("myPrintButton").style.display = "hidden";
// show
document.getElementById("myPrintButton").style.display = "block";
