Best way to calibrate your monitor, or to figure out if it's color scheme leans toward blue more than red, or green, is to put a page of white and black lines up and see how they look compared to a piece of white paper in real life in a sunny/bright room. If it looks dim or gray, then your monitor's tilted toward blue or is not as bright. If it's tilted toward a yellower tone, that means it's higher in green or red. And obviously, pink tone is red.
I actually calibrated my monitor for my new laptop to be as close in hue to my old one but I couldn't get it exact since the "brightness" power for the new laptop is literally more powerful than the old one. The colors may be the same, but it's just a super bright light. I actually work with the brightness at 90% or 85% instead of 100 because I'm so not used to my laptop being so bright. My desktop on the other hand is using a VIZIO monitor, and colors can be more saturated there.
A good template is also to print out an image with strong colors and then view it on your monitor with the print-out next to you. That'll help adjust the calibration to your personal eye. Do note that when scanning images, scanners do the same thing of "tilting" the colors one way or another, and it's hard to correct for this in PS levels, hue/saturation, and you will never get it to look exactly the same- but close. My scanner hate's blue with a passion, and loves reds, so all of my blues are scanned looking just a tad purple. It looks fine, unless you know what the actual drawing looks like.
for printing something you need to start your work in the color profile CMYK, since 90% of comic publishers/printers out there use that color setup. There are some ways to convert your image from regular (RGB) to the print standard of CMYK, but odds are it'll screw up your color composition something fierce. Some are fine, and some images will just be destroyed. It's better to start in CMYK. Unless you don't expect to print something ever, or know of/can find a printer that does RGB, then don't worry about it. One thing affected, aside from hues and colors, will be saturation of colors.
Personally, I don't print much, and what I do, can print fine in RGB printers. The only time I've had issues is when I got a test book from Amazon's printer CreateSpace and the image was mangled. (note that printers in general are all different. some print their inside of their pages lighter than others/ that is with less ink/ and so an image that's set-up to 80% darkness will actually look like it's set at 60% lighter and can ruin really dark moody comics)
