You can't.
你不能。
There is nothing in the standards that specifies that the select element has to have an arrow to indicate to the user that it has options to choose from, or how those options are shown. As those visual elements are not defined, there is naturally nothing defined for changing them.
标准中没有规定 select 元素必须有一个箭头来向用户表明它有选项可供选择，或者这些选项是如何显示的。由于这些视觉元素没有定义，自然没有任何定义来改变它们。
You just have to display a different element when printing.
您只需要在打印时显示不同的元素。

One idea: for the print operation, swap the combo box with a label control.
一个想法：对于打印操作，用标签控件交换组合框。

You could provide the selected text value next to the dropdown and hide it via CSS. Then use a print stylesheetto show the text and hide the dropdown when printing.
您可以在下拉列表旁边提供选定的文本值并通过 CSS 隐藏它。然后使用打印样式表来显示文本并在打印时隐藏下拉列表。
