We also have the problem where the printer occasionally won't turn on. Jayeff's solution worked once, and sometimes just unplugging and plugging in again works. However, today the printer would not turn on, so we plugged it into our APC Line-R 600 voltage regulator and the printer started fine. We found out two years ago that the voltage coming into our house was on the high side of normal most of the time, and our computer would exhibit functional problems. APC Line-R 600 is less than $50 at Walmart, Office Depot, and Amazon. The electric company, here anyway, will check your line voltage for free.
