I would suggest starting the article at: why print at 300 dpi? here's the technical reason.

We haven't seen 72 PPI for years. The majority of current LCD computer screens display over 100 PPI The 17" MacBook Pro actually displays 133 PPI. Please do look at modern monitor resolutions.

Photographs should be printed using an inkjet printer and most of these will benefit from being fed RGB images at the highest resolution possible. Why inkjet you ask? Well it might be expensive for large runs compared to some kind of press but frankly the conversion of your image to CMYK will saturate it and drop the overall gamut of the image considerably. May I recommend that if you're looking for a one off image then inkjet is the way to go, if you're looking for a large run then look at a digital press, they'll accept RGB images, they often have high(er) resolutions and some even print using a six colour process to expand oranges and greens.

The only point I would dispute would be the idea that mac monitors are 72dpi and pc monitors 96dpi. This used to be true when we had set resolutions on small monitors in the early days. Now we have high resolution monitors, showing much more than 72 dpi or 96 dpi. Great article. The only point I would dispute would be the idea that mac monitors are 72dpi and pc monitors 96dpi.

The file size will be four times as large if it's not compressed. But utilizing lossless data compression will usually significantly reduce that number. “A 1×1 inch 200-ppi image contains four times as many pixels as a 1×1 inch 100-ppi image and so is four times as large.”
