I was digging through InDesign CC 2015 looking for new features and found a quick little printing trick that, it turns out, was also in CC 2014.*
Ever want to just print the spread that you are working on? Instead of going to File > Print... and trying to remember what page is selected, just go to Layout > Pages > Print Spread... The print dialog box will open with the printing range set to the spread you are working on.
A nice little feature that I had no idea was there…
* And honestly, maybe it's been there forever. I really don't know.
