I was really way off!  LOL...

I will be interested is seeing what replies you get.  I'm afraid I am not  familiar with calibrating printers.  I have a print account with deviantArt that I hope to use some day for large framed art.

Please define what you mean by "large" art.    What size prints do you want to make?
