Epson Paper works very well on their inkjet printers. Luster is profiled.
www.inkjetart.com has a microceramic luster which I have profiled.
Lexjet in Tampa also has good paper and often is received the next day since they are so close.
The 9600 will take a 44 inch roll down to 8.5 x 11 paper. The 4800 will take up to a 17inch wide paper.
