This thread is asking for help automating printing and using Data Merge with Adobe InDesign (CS5), here it is.
First download threadless.zip
Edit data.csv as needed, open template.indd and choose Window>Data Merge from the menu. (Adobe Docs)
Click the little “Merge Documents” icon in this panel. It spits out an .indd with a page for each set of data.
Obviously for testing I didn’t set up nice fonts, etc. but you get the point. Read thru the Adobe Docs for the extra details.
Thanks to my lovely wife Kassie for pointing me in the right direction.
