Hello, I'm looking for a printer recommendation to replace our Xerox 7760. For the past few yrs, we've used this printer to support our design and photography courses, creating mock ups for photography books. We've had it for a few years and it's done an Ok job. We're looking for something with improved color control, ability to print on different types/sizes of media and front and back printing. We use Epson printers for exhibition quality printing, but want something closer to laser printer in terms of speed and front and back printing. Any suggestions would be greatly appreciated! Thank you
