Today Adobe have released Adobe AIR 2 Beta 2.

The Biggest Changes being:

Print Job Enhancements

New properties and methods have been added to the PrintJob class to give you better control of the way content is printed from an AIR application, including the choice of printer, paper size, and number of copies. New properties also give you more information about the printer, such as printable area, whether the printer will print in color, and whether the print job is currently active. The new PrintJobOptions.printMethod property allows you specify whether to use bitmap or vector printing. The PrintJobOptions.pixelsPerInch property allows you to specify the resolution of print jobs. The new PrintUIOptions class allows you to control how much the end user can change the page range to be printed. See PrintJob, PrintJobOptions, and PrintUIOptions.

TLS/SSL Sockets

You can now connect to a server that requires TLSv1 or SSLv3 for socket communications. See SecureSocket.
