HASH(0x980bbac8) out of 5 stars Makes scary noises 11 Jan. 2006
By Jeremiah@AWS - Published on
I am impressed with the print quality and the features. I have only two complaints: (1) The software installation is horrendous. Instead of using the normal windows installer, HP had to write their own cludgy dohickey. It almost never can find the printer on the network the first time (even if you can ping and load the HTTP interface), requires a reboot, and takes forever farting around doing who-knows-what. Printer driver software should not take 40 minutes to install. (2) It makes startling and disturbing noises. After printing, about 2-3 minutes later when it is nice and quiet, it lets out a gasp like someone who is startled in fright. Also, 3-4 times a day it runs through the initialization process and spends a good 3-4 minutes clattering around noisily. Then a little later it gasps in fright again. This device is not for the jumpy consumer. Combines poorly with heavy caffeine intake.

HASH(0x980bbdd4) out of 5 stars Bad drivers, very bad software, printer quality is good 16 Aug. 2006
By Br@S1L - Published on
HP traditionally has been a hardware company and it still shows in lack of attention for their software and drivers: a total nightmare.

I have worked in IT for 20 years and have come to love the quality and durability of HP printers, but when they try to make software for a more complex product such as this multifunction printer they miserably fail, as they have many times before with software and to a lesser extent drivers.

I have had the printer for nearly a year and had to try and set it up several times, it still don't work fully despite various driver and software upgrades and patches.

My impressions listed:

Quality of printing and copying once you get the unit to go is good, but you can't get the scanner to go and software installation is a nightmare:

1. It takes about an hour to install the software off the CD;

2. The full set of software is a close to 500 meg download (if you want to download an update), it is bloated but I don't know with what (it certainly does not function like a 500 meg piece of software);

3. Various items are installed including a so-called HP Toolbox which is designed in a strange way and which pops up at various times triggered by unknown events;

4. The scanner cannot be setup (I've never succeeded, despite downloading the "scanner fix" patch off the website and trying a number of times), so the printer functions as printer, copier, fax and data card reader but not as a scanner;

5. The software installation requires one or two reboots depending on choices; under Windows XP, this should not be required and is a nuisance after all the time taken to setup;

6. An "HP Update" tool installs as part of the setup that is supposed to download updates automatically at regular intervals. This typically starts to download updates, succeeds to get a few, then hangs midway and never gets anywhere. I have had this on several machines. This despite the fact that the tool successfully downloads an updated version of itself first;

7. The printer calibrates frequently and noisily even if it has been idle and not used. There is a setting in HP Toolbox to manage the calibration, however it cannot be switched off or made to be triggered by events.

The bottom line: HP should buy a software development company, or outsource its software design and development, partner with a company that understands software and the way people interact with software, or if design and development is presently outsourced, insource it.

But until they publicly announce a major change in the way they deal with their software, I won't buy this type of product from HP anymore.

HASH(0x980bbab0) out of 5 stars Good hardware AWFUL software 23 Aug. 2006
By Rob Brenart - Published on
The hardware is pretty good, print quality is great, speed is above average. The only real downsides to me on the hardware are the amount of toner I burn through and the noise, the rotating toner cartridges mixed with the constant initialization routine make this a noisy beast.

But the software, it's just awful. There's no excuse for it. I have 35 computers hooked up to this computer, and there are about a half dozen on which the printer is completely unusable because one of the monitoring packages decides to randomly gobble up 100% of the CPU (why do all 35 computers run monitoring software for a networked printer, no idea).

And the installer, what the heck are they thinking? This is a networked printer, I have 35 installations... some went smooth, those only took 15 minutes with 1 restart. Some took over an hour because the installer would hang in the middle of the process (and there's no good way to kill it) and had to be restarted... the record was 7 installs before it actually installed the printer. There's no reason I shouldn't be able to just click "add printer" and add the printing components of this printer, they went overboard on the installer and failed miserably.

HASH(0x980bbf48) out of 5 stars Thrilled to own it, but drink to forget the driver installation 26 Jun. 2006
By P. Haddox - Published on
After running this device for 3 weeks, I am still impressed with the performance and thrilled to own it. It is fast, reliable, easy to use and does exactly what it says it will do. The color printing of photos exceeded all expectations (fantastic for laser, but still not as good as a quality ink-jet).

Addressing negatives mentioned in other reviews:

Noise. Yes, it is noisier than a standard single-toner laser printer, but it is only as noisy as a bad ink-jet. I sit next to it and have no problems when my wife prints to it.

Network Driver Installation. This was just horrific. I am an IT Professional of 15-years and this is the worst HP driver setup I have ever come across. It took me multiple attempts to install the drivers on each machine because the software installer failed multiple times. It picked-up where it left off, but come on! Configuring the IP address was NON-intuitive. You think you can change the IP during the install, but you can't. You must use the random, auto-assigned IP during the installation and then use the web UI to change it (be sure to write it down during the install, because you can't find the web-based configuration screen without it!).

There was a wonderful video of how to physically set up the device, but the user was left entirely alone on the driver installation. The software is complete crud and HP should be ashamed.

Total installation time (box opening to printing test page): 2 hours

Now that the device is set up, I love it and would buy it again. You can't beat the quality and performance for the price.

HASH(0x980bd33c) out of 5 stars A fantastic product! Why go inkjet? 18 July 2005
By Dustin Hoffman - Published on
I couldn't be happier with my HP Color LaserJet 2840. I've had it for several weeks now and am still thrilled with its performance.

As the president of an IT firm, I've worked with most every brand of printer, but still cannot find any reason to recommend anything but HP printers. This Color LaserJet 2840 that I bought for my own personal use just continues that trend.

Firstly, ALL the features are usable over the network connection. This was important to me since I want everyone in my home to have access to all the features, and it's connected to my network. Scanning, faxing, printing, etc, all work great. (I knew printing would work, but was skeptical about the rest, especially the scanning).

The automatic document feeder works like a dream - I'll put 40+ pages in it and have scan them all into a PDF right from Adobe Acrobat 7. The scans come out crisp enough that Adobe's OCR gets most all the text on the page. Pictures scan nicely too.

The color output is fairly fast for an all-in-one, and warmup times are basically none. I use it for printing family photos, as the cost-per-page is a tiny fraction of an inkjet. If you want to use it for photos, I recommend using a good coated stock. It doesn't necessarily have to be HP brand. Color accuracy is good - much improved over the Color LaserJet 8550. I believe this is the same color engine as used in the Color LaserJet 9500. Even skin tones look good - especially after a bit of color correction in Photoshop.

I do have one minor complaint - it's a bit noiser than printing that you'd expect. Nothing that will stop a phone converstation or anything, but the four-toner-catridges-in-a-carousel mechanism is a little rattly when it's turning. I suppose nothing's perfect. :)
