If its a red hue then using the HSL in camera raw reduce the red hue slider. Use the eye dropper to get a custom white balance and check that the white is showing as colour 255 255 255. If not keep tweaking until it does say 255 255 255 or the 3 numbers are the same (or within 2-3 points either way) and in the 200 range. This way you know its colour correct on the computer. 255 255 255 actually means clipped/over exposed highlights and not detail but with paper should be fine. Another thing you could try is reducing the colour temp and hint

Don't forget that monitors are not all correctly set up colour wise. On my Laptop the RAW is showing a red hue but the JPEG is showing whites as grays. So its always best to check the colour codes first so you know whether its the monitor/printer or your eyes.
