Digital BW, The Print

Hi!

Considering the borderless prints, and printable area on paper 
media, what´s the main difference on these 2?

I might be better off with the 890 for b&w prints using Paul Roark´s 
curves, just have to find the ones that apply. Do Any of the curves 
that are posted on the MIS site (Paul´s workflows) work on 890?

Thanks

Miguel
