Batch printing and Date stamping

Hello, I am an accounts payable clerk and I'm looking for a couple solutions to make life easier for me. I get anywhere from 80-100 invoices per day. I'm converting them all over to emailing invoices rather than mailing. I find it easier to print than to open a stack of mail. So I am looking for a way to print many invoices at once. Currently I am getting PDF files through my Outlook. I did find a couple of ways but there are some flaws. First way, I found some script and created VBA and using rules, I set it to automatically print the invoices (without printing the email itself) and move the email to a folder. I found that 1 in every 10 files was skipped. I also tried a variation of this method that saved a copy of the attachment to a folder in my computer, but again, there were invoices skipped. Another method I tried is to select all the emails with attachments I want to print, then go to File/Print/ Print options, and check the box that says "print attachments" and then where it asks how many copies, I put 0. This prints just the files, but not the attachments. If anyone knows of another method I would be grateful. Also I am looking for a way to automatically date stamp the invoices that i am printing. The software that I have to use is Global shop, Outlook and Adobe reader. thank you!
