Colour laser all in one printer

Hi every one. I am in need of a good multifunction colour laser printer. following are my basic needs. Please advise

Duplex printing and scanning
high resolution
fast print speed
mac compatible
air print

i am confused between HP, Samsung and Brother.

Go with the HP. Both the Samsung and Brother color laser printers not only require toner cartridge change outs, but they also require the more expensive drum changes after so many copies. The HP color lasers incorporate the drum and toner cartridge as one unit and are less expensive.

Color laser printers have come down in price considerably, however, you need to factor in the price of consumables. Color toner cartridges are expensive although you can find refillable cartridges for less cost.

Dear chscag

thanks for reply. any recommendations about particular HP models meeting my requirements described earlier.

regards
