Re: HP
A laser may be more expensive to buy, but it sure as hell is cheaper to run. You'll probably have made that saving on a colour laser by the time you've had to replace your first set of toner cartridges.
I got a Brother colour laser, duplex, wired network and their implementation of PostScript, off our local classifieds for less than the price of even the shittiest HP inkjet. Status printouts and a test page were shown in the ad, indicating clumpy magenta toner and very little use. That clumpy toner was dealt with by merely transporting the unit home, and the (original) toners ran out several thousand pages later.
