Hi, I use a 2400 also. I'm no expert and you may already have your settings.Try this
Open file> to edit> to color settings, under work space : Adobe RGB 1998 ( if used )
under conversion options: Intent Relative Colormetric
In your Printer optins
under Color Handling : ** choose Photoshop manages colors **
under Color Management : ** Click ICM on, Click off/no color management
Pick proper paper profile*
Like I said. I'm no expert and there is more to this .....but my prints look "very" close to my calibrated monitor with these settings
Hope this helps, Mike
