Summary: I've had this printer for over a year. I owned a successful small business of 50 people and had all kinds of printers over 11 years. I love just about everything about this printer, except for the fact it bends one of the corners on every sheet of paper it prints.
Excerpt: I consider it a lost for not owning this machine the first time I saw it on the web. Let me explain, this inkjet printer prints out color pages very quickly, after I hit 'print', it did something different--it printed a color page for me faster than a laser printer can!
Summary: I have ordered this printer twice and had it arrive non-functional both times. The first time it wouldn't turn on (from printer house) the next time it had an error with the ink management system (from Amazon itself).
Summary: Purchased my first HP ProX451 in the Fall 2013, less than a year later it died on me. After researching the machine, I found out that there is a known problem with this printer. I contacted HP, and they advised they'd replace the barely 1 year old printer, with a refurbished unit.
Excerpt: The product is being used in an office of over 10 people for relatively high volume printing.
It's great that it is color and it is awesome that it is so fast!
There is really nothing I can say that is not so great...
