Have user adjust placement of fields

I am working on a Coldfusion page that prints a check. The problem that I have is I need to find a way for the user to adjust the placement of the fields. So if the amount that is being printed on the check is a little bit off the user can adjust the placement of the amount up to the left. When I first let some one test my work it worked great on one printer but it was off with another printer.
So I have been looking into creating a page where the user will be able to make the necessary adjustments.
I created a  jquery modal window that has up, down left and right arrows that calls a function on the parent page to say move up down left or right. I am trying to figure out how I can adjust the placement of the field. I tried using ImageDrawText so that I can make an image and possible set coords for the image but I can not find coords attribute.
I did a lot of googling trying to find something but I am unable to find something that will work.
