Write some software to automatically print files from a folder on my computer.

I am using ‘5 Minute Photo’ for my event photography system. This allows customers to select different photo print products to purchase. When the order is complete, the system sends the files to a particular folder on a computer running Windows XP Pro. The file names are preceded by the product type. E.g. Package A - [login to view URL] Print 6 x 4 – [login to view URL] What I want is for these files to all be send to a photo printer automatically and for the size of the print to be defined by the product type. So using the example above: If the “Printing” folder (or any sub-folder) contains a file which has the phrase ‘Package A’ at the beginning of it, then it will print that file in a number QUANTITIES of different SIZES. For example, for Package A files I need: 2 x 7cm x 6.3cm; and, 1 x 20cm x 30cm. In total there are only THREE different sizes that I could ever need to print. Once the file is printed it would need to either be moved into a different folder or it would need to have the filename changed so that next time the CRON runs it ignores that file. I would also want the files to be printed in REVERSE DATE order so that the oldest files are printed before the newest files. I can grant remote access to the computer in question for testing and also for you to see the nature of the ‘5 Minute Photo’ file system before starting the work.
