I'm looking into purchasing another laser printer, however, I want this one to be a colour one. here's what I'm looking for: High PPM in Colour AND B&W Has the ability to have upgradable RAM Is able ot be assigned an IP address and/or is able to be networked to easily. Has decent - good dpi for the colour printing and is below $2000 Is there a certain manufacturer I should be looking for? Any advice? Thanks!
