Great, what would be even cooler, however, is a script that does invoke the printer dialogue, once for the first file and then uses those settings for the rest of your files.
I work for an architect’s firm and when Preview.app used to be able to open multiple PDFs in one window we were able to batch print, say multiple A1 PDFs to a printer.
Currently I know of no way of doing this in Mac OS X Leopard. We often find ourselves printing dozens of PDFs and having to go through the print dialogue window for each file. Seems silly in this day and age of modern computing.
