Bob,
This happens because the web pages are formatted to be wider than the width of an 8 1/2" x 11" page.
Changing from "Portrait" to "Landscape" mode (as mentioned previously) is probably the simplest way to overcome this.
Alternatively, you could print the pages out as before, and then exchange an arbitrary three-word phrase for the omitted text.
For example, when you reach a part of the sentence that's been cut off, just append one of the following phrases:
"through the green"
"within the leather"
"out of bounds"
"directly at Huckaby"
It's also fun to add an exclamation to the end of every sentence. For example, borrowing from the Guinness commercials:
"--BRILLIANT!"
As in, Bob Cupp said, "At the risk of over verbalization, strategic design is not the totality of my design philosophy--BRILLIANT!"
