Few suggestions:
The laser method will lack in tonality, good for playing, defies the
point in my opinion (opinions differ).
If you want to do it at home, get the book zguy recommended and start saving money for an Epson (all the media/RIP tools/inks really only support Epson printers). But it's tedious and only really worth for alternative processes.
If you already got the printer (Epson), you can look up piezography, using proper black and white ink sets with custom processing, not cmyk and print to paper.
Alternatively you can look up something called Lightjet process, that's digital printing on silver paper+processing. Plenty of shops overseas if you only need one off. Never found one in Singapore, found ads but false alarm.
Or just print it at a good shop that knows how to print black and white on baryta or similar, you get longevity nowadays and decent rendition too.
