Start by going one lower - in your case, 11. The end result should be that your advice information all still aligns, and is not too big to push the check to the next page.

If this causes information to print too high, then you may need to tweak the advice section heights in order to get everything properly aligned.

You'll know this is the problem if your current problem has the first advice header aligning properly but the first advice footer is printing too low. This pushes down the second advice to also be mis-aligned and printing too low.

If this is not the particular printing problem, could you explain in a little more detail what portions of the check (and advices) are printing correctly - if any - and where the printing alignment goes awry? That will help us to give more specific information to identify the problem.
