Digital BW, The Print

I used to think that artist(oil, paint, mixed media, music) had the 
biggest listen problems. But with my recent experience(used to be 
production assit) printmakers are just as bad.  It is as if they dont 
hear a thing you say.  I say I want epson preiuem glossy b/w 5x7 
prints and they ony hear RC paper.  Yes I understand educating the 
customer but beating them down as they was stupid(citing print quality 
info that any competive customer can find on the internet) is crazy.  
What happened to educating the customer and giving them what they want?
