I haven't used it ... but the "GD Library" in recent user
contributions seems to do what you require.

Its done by merging images.
(Assuming win32lib is in use).
Define a pixmap with the same dimensions of the .BMP image.
Copy the .BMP image to the pixmap (bitBlt).
Use wPuts() to position the cursor and put the text into the pixmap.
Get the DC of the printer control (pDC = getDC(Printer) )
Start a new document on the printer.
Start a new page.
Now copy the pixmap to the pDC using bitblit technique.
End the page.
End the document.
and out it should come.
If I have time today, I'll knock up some sample code.
