i will be upgrading my inkjet color proofing asap. the printer serves as my large format or poster printer for indoor use and also as for contract proof and guide for our offset printing. i've tested both the hpz5200 and the epson 9900 and i am having a hard time choosing which is the better option. i hope i get comments and help. i print offset premium magazines with the inkjet proof as the approved guides for mass production. thanks
