All .NET printing is done in basically the same way. You create a PrintDocument, call its Print method and handle its PrintPage event. In the PrintPage event handler you draw your printed output onto the GDI+ canvas using the e.Graphics property. To draw an Image using GDI+ you can DrawImage. There are plenty of printing examples on the forum, the Web and in the MSDN documentation so I'm not going to provide another one here. A quick search will turn up plenty.
Also, to create the Image object in the first place you should call Image.FromFile. You must make sure you dispose the Image object when you're done though. The easiest way to do that is with a Using block:
vb.net Code:
Using img As Image = Image.FromFile("file path here")
'Use img here.
End Using
