Flex – Printing Support

lex provides a special class FlexPrintJob to print flex objects.

 FlexPrintJob can be used to print one or more Flex objects, such as a Form or VBox container.

 FlexPrintJob prints the object and all objects that it contains.

 The objects can be all or part of the displayed interface.

 The objects can be components that format data specifically for printing.

 The FlexPrintJob class lets you scale the output to fit the page.

 The FlexPrintJob class automatically uses multiple pages to print an object that does not fit on a single page.

 The FlexPrintJob class causes the operating system to display a Print dialog box. You cannot print without

some user action.

Prepare and send a print job

You print output by preparing and sending a print job. Let's create an instance of the FlexPrintJob class

var printJob:FlexPrintJob = new FlexPrintJob();

Start the print job

printJob.start();

Flex will cause the operating system to display a Print dialog box. Add one or more objects to the print job and

specify how to scale them

printJob.addObject(myObject, FlexPrintJobScaleType.MATCH_WIDTH);

Each object starts on a new page. Send the print job to the printer
