Here's how I cratered XP. It didn't just lock up, it died. Nothing worked, no keyboard entry, nada. I had to power cycle.
1. Enable the obscure print background setting for IE (advanced options).
2. View a Google Map in Hybrid view (sat and map).
3. Print to Adobe Acrobat (probably works for regular printer as well but I don't have time to power cycle my desktop.)
When you do the same thing in Firefox you get a smear of blurred color, but neither FF nor XP craters. Interesting lesson about the stability of IE.
The best printing browser, hands down, is Safari. IE and Firefox used to be tied, but I'd say FF is ahead now. I'll have to try this experiment with FF and Safarin on my Mac and see what happens there.
I think Google Calendar might generate PDFs to print via a PDF viewer. Given the state of the browser, Google Map probably needs to do same thing.
