HP 400 Reviews

Reviewed by 4 customers


Solid product. Could be better.


from New York, NY  -  Value Oriented

We were replacing an HP M3035 that was 4 years old and not worth repairing. The M475 is much sleaker in design, but seems to give up some speed to our old machine, which was surprising and disappointing. Copying or scanning really causes the machine to sound as if it has to think about the function to get it completed. For the price point I think it is a good machine, but the sound and the slower production would cause me to spend up next time around.


Great printer


from Brooklyn, NY  -  Frequent User

We've only had it two weeks but we've been very happy with it so far. The toners are affordable though I wish that more than just the black toner came in high yield. Also wish that it could print full bleed but we are so happy with it otherwise we don't care about that.


I like it.


from Connecticut  -  Heavy Duty User

This is replacing my hp 3300 which I had for ten years. I am happy with how quickly it prints.
