Digital BW, The Print

I posted this a couple of days ago and got no answer, so here goes 
again. I printed a B&W in RGB without using any curves and it printed 
quite nice (I forgot to apply curve) After appling the MW curve I 
noticed an increase in contrast. It didn't match the monitor but the 
one without the curve matched. Any ideas on why there would be a 
contrast change

I believe this is correct, but am a relative newbie myself, so Caveat Emptor:

The printer output would not match the monitor because *.amp curves are not WYSIWYG (What You See Is What You Get)... they affect printer outpud independent of what the screen is showing, which is often in colour anyway, and immaterial to a printer producing grayscale output.

There would be a difference in contrast... one way or another, because that is what curves do, they remap the amounts of each different element (RGB or Grayscale level)in the image.

Do you have Photoshop? If so, read up on curves. They are very handy, and you can make your own very easily, although the ones I have produced are only useful for the individual image for which they are produced.

Robert, thanks for the help, I didn't want to try readjusting Pauls 
curves but maybe that is the way to go. I will try it and let 
everybody know. Thanks again
