Windows: Got a host of PDFs, Office documents, or, heck, AutoCad documents to print out? Load them into PrintConductor, and you can batch print them without opening the apps they came from. Better still, you can print them all to PDF.
PrintConductor doesn't require much more explanation. You can team it with the Universal Document Converter print driver to batch-process all your documents into PDFs, but you can also use your own virtual printer driver, like doPDF. If you're planning to print the same batch of documents more than once, you can save your queues to a file for later loading.
PrintConductor is a free download for Windows systems only. Already have a batch PDF conversion process you prefer? Share it with your fellow document shufflers in the comments.
