Property Detail

pageHeight

property
pageHeight:Number  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The height of the printable area on the printer page; it does not include any user-set margins. It is set after start() method returns.



Implementation
    public function get pageHeight():Number

pageWidth

property 
pageWidth:Number  [read-only]

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

The width of the printable area on the printer page; it does not include any user-set margins. This property is set after start() method returns.



Implementation
    public function get pageWidth():Number

printAsBitmap

property 
printAsBitmap:Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Specifies whether to print the job content as a bitmap (true) or in vector format (false). Printing as a bitmap supports output that includes a bitmap image with alpha transparency or color effects. If the content does not include any bitmap images with alpha transparency or color effects, you can print in higher quality vector format by setting the printAsBitmap property to false.

The default value is true.



Implementation
    public function get printAsBitmap():Boolean
    public function set printAsBitmap(value:Boolean):void

Method Detail

addObject

()method
public function addObject(obj:IUIComponent, scaleType:String = "matchWidth"):void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Adds a UIComponent object to the list of objects being printed. Call this method after the start() method returns. Each call to this method starts a new page, so you should format your objects in page-sized chunks. You can use the PrintDataGrid class to span a data grid across multiple pages.

Parameters

obj:IUIComponent — The Object to be printed.
 
scaleType:String (default = "matchWidth") — The scaling technique to use to control how the object fits on one or more printed pages. Must be one of the constant values defined in the FlexPrintJobScaleType class.

Related API Elements

send

()method 
public function send():void

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Sends the added objects to the printer to start printing. Call this method after you have used the addObject() method to add the print pages.

start

()method 
public function start():Boolean

Language Version: ActionScript 3.0
Product Version: Flex 3
Runtime Versions: Flash Player 9, AIR 1.1

Initializes the PrintJob object. Displays the operating system printer dialog to the user. Flex sets the pageWidth and pageHeight properties after this call returns.

Returns
Booleantrue if the user clicks OK when the print dialog box appears, or false if the user clicks Cancel or if an error occurs.
