How do I control a printer to print on pass

[VI_Joe]

My customer wants to print a label every time a unit passes the test.  He wants me to provide a control signal from my LabVIEW application that will start the printer.  How do I do that?  I'm using compact DAQ and DAQmx.

Thanks in advance.

It's going to be a bit difficult to answer the question if you haven't told us what kind of printer it is. It's not likely that you will need to resort to using raw digital signals to control the printer. You could just send it a page to print.
