Tell us about yourself!
You know what's interesting about this? The printer design you chose is actually a very generic design. It is used for printers from Samsung as well as Dell and probably many others. In fact, your local Micro Center has this printer available for $30- it's the Pantum P2500W.
I'm not sure how lethal this is. Remember, the static shock you get when you touch a doorknob after walking across carpeting is tens of thousands of volts. But the current is very tiny (pico-amperes, if that) and is exhausted in tenths of a second. Something like this printer power supply gives off micro-amperes (perhaps milli-amperes). I still would not touch it- it might induce a heart attack- but it's nowhere near as dangerous as 2kv at 10 amps.
