You can convert the non-film (Matte Black) versions of the Stylus Pro 7450 or Stylus Pro 9450 printers to work with Photo Black ink instead. This article explains how to achieve this by updating the printer's firmware.
Preparations and precautions
Once the unit is converted to Photo Black from Matte Black, it will no longer work with the Epson driver. You will need to obtain a supporting RIP to use the printer thereafter.
The firmware procedure must be followed exactly, otherwise you may corrupt the firmware update and seriously damage your product. Do not use this update for any purpose other than as stated.
Neither EPSON nor its affiliates will take any responsibility for any damages that result from a firmware update. Your use of this document and any related firmware file(s) is at your own risk. Any resulting repair will NOT be covered by your warranty.
You may need to install Microsoft .NET Framework Version 2. Click here to download and install it.
If you require further support on carrying out the firmware update, contact Epson.
