I guess that'll work...the folks at the office will just love me tying up the printer while I'm doing this. Seems silly since just about every other user manual on the planet comes as a .pdf (yes, that's a gripe!).
I do have Adobe Pro but printing out each topic is ridiculous. Also Adobe changed the text to gibberish in the pdf. I was hoping someone had already fumbled through this. Oh well.
