What I have found that works best for me is to get the view I want in GTDNext (could be all tasks, or Next tasks, or Focus tasks, or tasks for just one project), then grab a screen shot of that (using the Windows Snipping tool or other similar utility) and send that to my color printer (so Next is green, Focus is red, etc.).
I then use that printout as a check list that I can even write notes on (like when during the day I want to get that done, etc.). Then when those tasks are done, I can log back into GTDNext and mark them as completed. I know it adds the extra screen-grab step (instead of just printing directly) but it only takes a few extra seconds and works pretty well.
Have others found tricks or workarounds for this?
