All Implemented Interfaces:

PrintHandler

public class DefaultPrintHandler
extends java.lang.Object
implements PrintHandler

Default implementation of PrintHandler that displays standard Java Print dialog and modify default settings with the settings that end user selects in the dialog. From the print dialog this implementation reads only printer name and update print settings with the selected printer name. Also this implementation enables backgrounds printing.

If you need to modify this default behavior, then you can create your own implementation of the PrinterHandler and register it using Browser.setPrintHandler(com.teamdev.jxbrowser.chromium.PrintHandler) method.

PrintHandler的默认实现，它显示标准Java Print对话框，并使用最终用户在对话框中选择的设置来修改默认设置。此实现从打印对话框中仅读取打印机名称，并使用所选打印机名称更新打印设置。同样，该实施方式能够进行背景打印。如果需要修改此默认行为，则可以创建自己的PrinterHandler实现，并使用Browser.setPrintHandler（com.teamdev.jxbrowser.chromium.PrintHandler）方法进行注册。
