…seem to have its content carefully laid out so that if you print a hard copy, there is one line of text that forces you onto an extra page?
I dnt know, but it annys me als 
I always print out web pages and e-mails one page at a time. If I have access to a preview function (as in IE), I use that; if the last line were crucial, I’d either print it on the other side of the page, or else copy and paste the text into Word and play with the margins or text size so it would all come out on one page.
I do a similar thing - I almost always print to .pdf (thought this is partially due to an inconsistent printer driver), and then crop the unneeded parts.
I imagine the reason may be that the browser may be adding margins to the pages, or they are laid out to exactly the size of a page but won’t all fit right to the edge.
That, or all the websites are designed for A4.
On the topic, what’s the deal with “You will be redirected in 10 seconds.”
Redirect me NOW! I always click the link anyway.
It’s so, if you’re landing there from a bookmark or similar, you can be informed that the page has moved. That way they don’t have to keep the redirect page up indefinitely. It’s like the telephone recording that tells you that the number has changed, and then connects you: if you weren’t informed of the change, you might go on thinking the old number was still correct, and be caught by surprise when it changed.
Funny, I find that the new IE7 will print every thing in one page. Of course, you may get two inch margins and type too small for these old eyes to see clearly. 
You slay me. 
Nah, I use A4 paper (I like it better) and I still get this.
