Webtoon: print later?

I should have attended the meeting and asked this
question.  My bad.

In Japan, the vertically-scrollable manga by comico is quite
popular.  However, in my understanding, they assume
that they might want to later print comico manga on
paper and sell it as traditional manga books.  This means
that comico manga authors always have to worry about
page boundaries.  Does the same thing happen in Korea
and France?  Or, do you completely ignore the possibility
of printing on paper later?

Makoto
