The approach we have for paging so far is that it is done automatically when needed. The attached PR extends this mechanism to print (and a few related commands). Thoughts?

[thockin]

oh, I didn't know about transcript. That's what I need.

Whatever existing paging we have did NOT kick in when printing my large object. That PR looks like it would fix it. How does paging intersect with transcript? :)

It wasn't applied to print, deliberately.

It'll write to the file everything you see, at least.
