Printing a line repreatedly

I'm trying to print lines until the bottom of a page - sort of a lined page
effect.

First I added a shape object to a detail band and tried to duplicate it
before printing - no go.

Next I tried to add lines to a memo object in a detail band - this could
work but I could not figure out how many characters to add so the line
filled the page width.

Would appreciated any ideas
Russell.
