Self-explanatory. It appears the printer struggles when it comes to block orientations. Oftentimes you do not really care about the orientation of the block. For example, I've been trying to print a giant custom tree, which uses Cherry Wood (6-sided log). I do not care how the logs are oriented. I've noticed that the printer fails to function entirely due to this. Would be very handy if there was an option to ignore orientation.

I could also use this, it would be really useful for building large creeper farms and such things.
