Steve, LabVIEW may not be populating your graph when you call the subVI. It's possible that you will have to open the front panel, print the graph, then close the front panel. This is particularly the case if you are using an older version of LabVIEW (pre-5.0). Knowledge Base (KB) 18FB2692 explains

Well I spoke too soon. It works when the print graph vi is open. When I put the whole package back together the vi is not opened. In this case the graph prints without data. It is almost as if the "print panel to printer.vi" is evoking a different copy of the print graph.vi where no data is gett

Ah, this is why no one has understood me! Yes, I have the graph on a nice looking front panel then I offer a control to print the graph. This calls ANOTHER graph vi, that has a vary similar front panel but with white background and black graph and data to be a little more printer friendly. It wo

Why is there no way to pass data to the graph? That sounds like your major problem and not the printing. Do you have a connection on the subVI's connector pane? Is the subVI not visible when you want to do the printing?

I am trying to use the NI library function "Print panel to printer.vi" sited at http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=B45EACE3E9F956A4E034080020E74861&p_node=DZ52084&p_source=external. The vi that I want to print is a graph that I must pass parameters to that contain the
