The following list further illustrates the relationship between units of measure.

• 1 pixel = 20 twips

• 1 point = 20 twips

• 72 pixels = 1 inch

• 72 points = 1 inch

• 567 twips = 1 cm

• 1440 twips = 1 inch

To scale a movie clip before printing, set its

MovieClip.xscale and MovieClip.yscale properties before calling

this method, and set them back to their original values afterward. If you scale a movie clip and also pass a value for

the

printArea property, the pixel values passed to printAreareflect the original size of the movie clip. That is, if

you set a movie clip’s scale to 50% and specify a print area of 500 x 500 pixels, the content that prints is identical to

the content that would print if you didn’t scale the movie clip; however, it prints at half the size. For more infor-

mation, see the addPage (PrintJob.addPage method)method of the

printjob classin the ActionScript 2.0 Language

Reference.

Specifying printing as a vector image or bitmap graphic

The options parameter lets you specify whether to print as a vector graphic or bitmap image. When using this

optional parameter, use the following syntax:

{printAsBitmap:boolean}

The default value is false, which represents a request for vector printing. Remember the following suggestions

when determining which value to use:

• If the content that you’re printing includes a bitmap image, specify that the print job print as a bitmap to include

any transparency and color effects.

• Conversely, if the content does not include bitmap images, specify that the print job print as vector graphics to

take advantage of the higher image quality.

Specifying a frame to print

The frameNum parameter lets you specify a frame to print. If you do not specify a frame number parameter, by

default the current frame of the target or level that you specify as the first parameter when you add a page prints.

Print or delete the print job

1 To send the print job to the printer after using the ActionScript 2.0 addPage() calls, use the PrintJob.send()

method, which causes Flash Player to stop spooling the print job so that the printer starts printing.

2 Todeletetheprintjobafteryousendtheprintjobtoaprinter,usethedelete PrintJob() ActionScript function

to delete the PrintJob object, which frees memory.
