What are the pros and cons of the Epson 4000? I think about it mostly because of the print size. In particular, I am doing medium format, and, believe it or not, I like the square format (which is no crime, I hope). This means that on an A3 printer I am losing about 4 inches or so in each direction, which makes a difference. Thanks in advance for your comments, in particular to Bill, who I know is the proud owner a 4000 (and, what's more, he actually uses it). Nobody
