Graphics on printer canvas

I am currently working on a project where I plan to print (through printer
canvas) a large number of "reports" containing summary statistics from
different subsamples.  Each report should contain a simple graph based on
the same data, and I thought of using one of the sample OCX's included with
Delphi 2.0 to produce the graphs.  How do I include one of these graphs on
the printer canvas ?
