Never heard Dupont makes inkjet papers. Where did you get it from? Is there any information you can get from where it is sold? BTW, Dupont is the company that makes the best white pigments in the world. THe best black pigment is however, made by a Germany company. I wasn't told the name of it though.
Bought 100 sheets from eBay (item# 170088591868). Seemed to be priced well! Still waiting delivery. Via Google searches, looks like they make it for Epson...
Just got it today. 100 sheet of basically single weight glossy photo paper, 13" x 19". Very well packaged! $33.39 = $8.95 UPS shipping to the door. Shoulda bought two and reduced shipping per sheet considerably!!
Tried it on my Canon i9900 using Photo Paper Pro Glossy and it is FANTASTIC!! Works GREAT!!
