Add a daily "Email My List" option, a la Nirvana. Great for printing!
Yes, some of still PRINT, but most To-Do apps have meager printing capabilities, including GTDnext and Nirvana. HOWEVER...
Nirvana has a GREAT "email my list to me" feature that largely overcomes its in-app printing shortcomings. You can choose to receive your nicely formatted list on any day(s) of your choosing. For me, it's a daily reminder to process my list, print it out for my shirt pocket, and then archive the email for reference.
James, 'Export All' is a partial workaround for those of us who want our info in print. Please add "Email My List" as a preference setting. Easy, 'set it & forget it' functionality!
