I was curious if there was any speed or quality advantage to printing cut sheets landscape vs portrait on the large Canons (PRO 2000/4000). I generally print portrait because the cut sheets clearly were cut from a spool in that direction and I assume the printer is better at handling the curl in that way. But I could imagine it would print faster the other way. Lets assume there's enough of a margin that I'm not worrying about the unprintable area.
