Here's a thing I found Microsoft to be very restrictive about, and not letting me do my own things with PCs.
A few months ago I tried to print out a UK £10 ten pound note and a US $10 ten dollar bill so I could show the students, using a school Windows XP computer. Windows wouldn't let me do it because I was trying to print an image of a banknote, i.e. it assumed I was a counterfeiter and criminal.
Apparently there's DRM in Windows printer drivers that blocks the printing of currency images.
This is something that anyone can try for themselves, try printing out an actual size colour image of a banknote in Windows and see what happens.
It's this unique pattern of dots that Windows detects and stops the image been printed. I'm sure it's the same with Mac OS X as well.
just about all banknotes have it.
