You need the True Black and White software for the Canon and you need an Eye One to relinearze one of the existing curves for gloss papers. That is essential I see after doing it.
Then you have something as good or better than the Hp for BW.
6 years in and all my prints on HP Prem ID Satin look great. Some displayed behind regular (not museum) glass getting some sunlight. Some just in clear bags getting some indirect sunlight. Some kept in drawers.
Bowhaus says they will make a Windows version of the True Black and White, so hopefully that is true and not too far out. Was tough call to not get a z3200, but looking forward to getting to know the ipf8300.
