White background isn't printing white

[Ty283675097vi2]

So I am having an issue getting my photoshop colors to match when I am printing. The white background is printing more as a gray color instead of a photo paper white. The green is also slightly darker if someone could help me in editing this that would be great I have the colors picked out with color chips just cant get the printed copy to match.

Thanks

You should always test output using good color reference images designed for that task. The color reference images RGB values are such that they are set for output and are editing and display agnostic. Test the output this way and examine for the same color issues so we know it's not your image-specific issues causing the problems:

A possible clue is that the background is already showing up gray in the Print preview that you posted. If you open the Info panel and then hover the pointer over the background, what is the color value reading?

Also, what is the green color value you are specifying? It looks fluorescent…it might not be reproducible using CMYK ink or toner.

@Ty283675097vi2 IF the "white" is actually RGB 100,100,100 then it SHOULD print white, but colour management is involved too. You need an accurate printer/paper profile and select it in Photoshop when printing. 

Also if you'd like to see accurate colour onscreen you need to calibrate the profile the screen.
