Still trying to figure out how to disable this annoying 'feature' (and yes I've tried several 'Google' solutions, so far to no avail)

Toner Save Mode, and Reduce Paper Curl, are excellent features which work extremely well

All features seem to work fine including duplex printing

That's a very good feature.

prints great and love the 2 sided feature that it has.

I love the auto-duplex printing feature as it saves me 50 percent on paper costs and gives me the convenience of carrying less paper when I'm on campus.

Toner Save Mode is a very valuable feature because with cheap paper some of the printing will show through, and by reducing the amount of toner applied to the paper, it helps a great deal, and is a great feature

After years of being frustrated with ink jet printers and ones with fancy features like wifi - I just wanted something simple that worked when I needed it to

Love the duplex feature and the printing is sharp.
