Question about Printing

HI I am writing a small program to print a report. There is a need for an 
underline for each new item. There is also an underline for those items with 
more than one line, i.e. more than one lot # per item. As such when the page 
breaks to the next line, often it starts out with an underline (after the 
headings), belonging to the last print line of the previous page. This program 
is written using the cycle time logic. I am thinking of keeping a counter of 
lines printed and checking it prior to printing an underline, but there must be 
some better way I hope.
Thank you,
Rob
