As you have already seen the other messages, this is just an endorsement to *avoid* JPEG for anything that contain pixels that are next to each other and have sharp color transitions ... as happens with lines and drawings and text, etc.
No matter what "quality" you save the JPG with such content, the results will not be great. Basically, the transitions from one color to another at the edge of such objects get speckled dots - sometimes more than a few pixels far from the color transition - and also additional "transition color" pixels on both sides of the color change locations. These extra dots then show up in the printed output (if it is a high-quality ink-jet or any color laser) and, depending on the colors, can be pretty obviosu. The text and lines get smeared - the sharp transition between the text color and the background color gets softened. In the worst case, narrow lines disappear or get broken up pretty badly. Bottom line: JPEG's are fine for pictures, but even there, using a high-quality JPEG (from a non-lossy source image ideally) is important - repetitively editing and saving the JPEG from image editor programs can increase the "noise" in the JPEG over time.
