Note: Any ActionScript code that needs to be called to change a resulting printout must run before the

PrintJob.addPage() method is called. The ActionScript can, however, run before or after a new

PrintJob()method. If a frame has a call to PrintJob.addPage(), the call itself does not guarantee that the Action-

Script script on that frame will run when that frame is printed.

Note: For information on printing from SWF files at runtime using ActionScript 3.0, see “Printing” in Programming

ActionScript 3.0.

Specifying a target

The ActionScript 2.0 target parameter can be either a number that represents a level (such as 0 for the _root

document), or a string that represents the instance name of a movie clip (

"myMovieClip").

Specifying a print area

The optional printArea parameter includes the following values:

{xMin:Number, xMax:Number, yMin:Number, yMax:Number}

The xMin, xMax, yMin, and yMax values represent screen pixels relative to the target level or movie clip registration

point. The print area orientation is from the upper-left corner of the printable area on the page. If the print area is

largerthantheprintableareaonthepage,theprintdatathatexceedstherightandbottomedgeofthepageisclipped.

A. Paper rectangle B. Page rectangle C. (594,774) D. (576,756) E. (0,0) F. (-18,-18)

If you don’t specify a print area, or if you specify an invalid print area, the print area defaults to the Stage area of the

root document.

Scaling, points, and pixels

A print job using the PrintJob class prints Flash content, by default, without scaling it. For example, an object that is

144 pixels wide on screen prints as 144 points, or 2 inches wide.

One point equals one pixel. In the authoring tool, 72 pixels equals one inch; on paper, 72 points equals one inch.

To understand how Flash screen content maps to the printed page, it helps to understand screen and print units of

measure. Pixels are a screen measurement and points are a print measurement. Both pixels and points equal 1/72 of

an inch. A twip is 1/20 of a point and pixel.
