iText 5 Replacement for Class com.lowagie.tools.Executable

Dear Reader,
I have legacy code which invokes method printDocumentSilent of class com.lowagie.tools.Executable.
I wish to upgrade the iText library we are using.
We currently have itext-2.0.4.jar
I wish to replace this with itextpdf-5.1.2.jar
What methods of what classes in iText 5 replace method printDocumentSilent of class com.lowagie.tools.Executable ?
Do I need to download another JAR file that contains the replacement class, or classes ? If so, what is it called and from where can it be downloaded ?

Thank you,
Avi.

This has nothing to do with your problem, but are you aware of the licensing change that came into effect for iText 5? You will most likely have to buy a license to use it for business purposes.

Tim,
Thanks for the heads up. The application is entirely in-house and used only within our organization.
I resolved the problem by using the java class java.lang.Runtime to execute the following command:

AcroRd32 /t {PDF file to print} {printer name}

Note that this command launches Acrobat Reader, opens the supplied file and immediately prints the file.

Cheers,
Avi.
