I don't think I've come across (official) printer driver software in a long
time that wasn't extremely tacky, garish, and completely useless. I usually try to find a way to extract just the necessary driver files, as I can't stand that "value-added" crap
. Goes for my Pixma ip2600, but at least the printer works decently, and I didn't have to work too hard to get the non-crap files (found a clean Vista driver that works on Win7, rather than the überbloated Win7 driver).
It sucks that there's so much poorly programmed software that b0rks with DEP enabled - it's due to bugs or pesky compression/protection software that's trying to be a bit too sneaky for it's own good. With such a relatively
short list, I'd personally add DEP exceptions and keep EMET installed, though.
