Add bulk print feature to Python Web Scrapper

I need this done VERY fast. This is an urgent project.

I have a web scrapper that generates Word documents. It generates letters, and mailing envelopes. I need a feature that prints the letter, and the matching envelope out. So I need a bulk print feature.

There are 2 folders:
Folder #1 is Letters
Folder #2 is Envelopes

So when you run the print command, it should send every letter and envelope to the printer, in order.

For example: When you hit print, it will go: Letter 1 > Envelope 1 > Letter 2 > Envelope 2 > Letter 3 > Envelope 3.

So it will just print both folders out in order, matching the letter with the envelope.
