I have an Epson Stylus Pro 3880 wide format printer. The Epson Ultra Premium photo paper (17"x22") works perfectly for the applications I need. But at $55 to $80 for 25 sheets, it's a little costly. I was advised by a rep from Epson not to use the rolls as they could damage the printer (and I don't want to compromise my warranty). Are there any other proven products that are comparable to the paper I'm using now but at a lower price?
