Why do you think so ?

If you ask me, it's perfectly doable without any changes.

There is a demo that shows how to print a text by splitting it in lines, and
simply printing a band per line. That will have the same effect as what you
seem to need.  Basically, it means using a TStringList as a data source
for a (sub)band instead of using it as the text of a single memo.

What you may need to do is to split the text "correctly" over the lines of the
TStringList, but that should be easily doable. All you need is a function to
calculate the length of the text.

I think this is perfectly doable without any changes to the original code.
