Problem: You need to scan something with print on both sides of the page but your scanner only scans one side of a page. Something like a bank statement is what I’m after.
Solution: Automator to the rescue! Automator is included with your Mac and you likely have never used it. It’s really cool! I set up what you see here and with Image Capture I scan the odd pages and then the even pages, saving them to separate files. Running through this Automator workflow, I’m prompted to first pick the odd pages, then the even pages. Automator then interleaves the pages together and pops up my combined PDF in Preview. I can then save it off.
