Digital BW, The Print

One process I did with my film cameras was to match my cameras (and films) 
to my printing.  This meant knowing the times to produce absolute black with 
a clear negative, then with a full-zoned subject.  This took into account 
variables of camera, film, development time, enlarger, paper, etc.

My questions is, once I get my Epson 220 set up and printing steps 
correctly, should I then control for the digital camera variable? It seems 
that cameras might meter differently, creating a need for some modifications 
on the printer.

If so, I could shoot an image of a target that included absolute black, pure 
white (doing a white balance on it, of course), and some mid grays, 
including an 18% card.  Then, upon printing the image, I could tell if the 
printer was matching what the camera recorded.

Crazy? Sane? Irrelevant?
