Hey, I understand that resolution stuff a little bit and then I don't at the same time. I have a picture that is 11842 X 1472. What would be the printing size of that one? 10 X 30? Help.

This is exactly what the article was talking about, just knowing the resolution isn't enough to say what print size it would be an 1842 x 1472 picture (assuming you typoed the 11842) is
5.117" x 4.089" at 360 ppi 6.14 inches x 4.907 inches at 300 ppi 7.675" x 6.133" at 240 ppi and 12.28" x 9.813" at 150 ppi
(where ppi is the numbers of pixels per inch.)
360 ppi is the normal suggested value for best quality, but you can certainly print with fewer pixels per inch, you just might not get such a sharp result.
Your printer on the other hand lays down dots per inch, or dpi and more than one dot goes to make up one pixel, so you should use your printer at about 1440 dots per inch, while providing an image with 360 pixels per inch. That means that for every pixel in your image your printer puts down 4 dots.
Another useful guide is that your ppi setting should be an integer multiple of your dots per inch, so that your printer software doesn't have to interpolate further to use say 3.12 dots for each pixel. So ppi values like 360, 288, 240 and 180 ppi are the best to avoid further resampling when printing at 1440dpi.
I get successful photo prints at just about anywhere above 200dpi. Granted, more dpi is better, but the quality has certainly been acceptable at 200+ dpi :)

A lot of that depends on the printer as well. Photographic print machines are a lot more tolerant than inkjet printers. On a lightjet you can easily use 150ppi images without problems, as the print process interpolates much more seamlessly than the drivers in an inkjet printer. It depends how the image is created on the page.

actually I didn't typo the 11842. I took a picture that long and was wondering how long I could make it. In Photoshop it says that it is 7.8 inches by 59.9 inches at 200 ppi. I don't know how to change the ppi higher to see what it would be. Then it might be way to skinny to make it more ppi too.
