First off, I would give this 4.5 stars out of 5 if half stars were available. The ding is only 10%, not really 20%. *smile*I got this printer extremely quickly, so that put things on the right foot (already five-starred the vendor).Unpacking -- Everything was easy to unwrap, and the handy reference card above the toner cartridge had easy to understand pictures on what tapes and brackets to remove (the orange color-coding helped, too). The instructions rated the initial "starter" cartridge at 1600 pages (if I read that correctly), which is way more than I expected for a starter. Five stars.Physical Setup -- No large power supply on the cord, the bulk is built into the printer. That's always nice. Power and USB hookups happened to be on a desirable side of the unit for my desk area, easy to find and easy to plug in. Five stars.Software (INITIAL SETUP) -- Here's the ding. On Mac OSX Lion it is hard to get things working. I have seen various lists for OSX setup, but I am not sure if those are for Snow Leopard or Lion (I think they are mainly for Snow Leopard, 10.6). In my research, there did not seem to be much enthusiasm for Lion (10.7). This is pretty silly. Lion has been out for a decent amount of time, and while I understand it has some substantial changes under the hood, HP should have this figured out with a downloadable update so that Lion users can get this done more easily. Luckily, I have a dual-boot Mac (Boot Camp should work, I didn't try a virtual machine route, like Parallels or VirtualBox) with Windows 7 on the other side. I booted into that, and every bit of software setup worked immediately and flawlessly as soon as I turned on the printer. I installed the base software and the updated firmware (that was seamless and fast, all built into the HP wizard), no issues. Booted back over into Mac OSX, and my iPhone, iPad, and Mac itself could see the now-AirPrint-enabled printer. So, five stars for Windows, three stars for Mac 10.6, and I have to say zero stars for Mac OSX Lion (10.7). Sorry.Software (after initial setup) -- Wonderful stuff. I love a browser-enabled interface because it is flexible, easy to access, and rich in information (I'm also a techie, so YMMV). The interface here is fast and clean. You can give the printer a manual or dynamic IP address (I went manual, so even if I move the machine around the house and power down/up a lot, I am sure to be using the same network address). The data captured for the printer ranges from total number of pages printed to estimated toner left to network minutiae I didn't even understand. And the network interface was accessible via Firefox by just entering the URL or by clicking a button from the Mac's own printer properties (which set up immediately when I booted back into Mac). Wonderful stuff, an easy five stars.Printer Build Quality -- The power button feels plastic-y and there is no doubt this is more consumer grade rather than business class. Then I remembered I payed $96 for a laser printer, and realized it all works just fine. Five stars. I like the second tray (above the main feed tray). I imagine it will be nice for things like pumping out envelopes without having to mess with a separate feeder tray on the back or changing the main tray. Everything just loads from the front into two separate feeders.Printer Print Quality -- I haven't had a laser printer at home for almost ten years, so I am obviously pleased as punch with how fast sheets come out (even from powered-down state) and how great they look. And while I know toner can be pricey, there are so many discount folks who sell these carts, that even if the quality is slightly less or fewer pages are yielded, it's still extremely affordable. I found a 2-cartridge pack for $25, making laser printing far, far cheaper per page than my previous ink-jet (even at discount ink-jet prices). Five stars.Printer Configuration -- I have seen some people talking about power down/power up issues, but I'm not sure what they are referring to (perhaps a flaky wireless connection?) This printer prints very quickly even out of a powered-down state, and I like that it shuts off when idle for a time to save on power. No complaints as long as the wireless signal is strong (since I assume things degrade in this regard if the connection is marginal). Five stars.Printer Form Factor -- I really like the small footprint on this. The printer looks a bit goofier when all the input and output brackets are unfurled, but it is still a handsome piece. I like how it looks, and I think it will fit wherever we need it to. And as I mentioned earlier, the power cord does not have a large "wall wart", so any place there is a wireless connection and a power outlet is a place you can put this printer for use throughout the house. Five stars.In summary, if HP would get an easier way to get this up and running on Mac OSX Lion, five stars would barely contain my enthusiasm. But having just about no way at all for that to work on Lion (and not being entirely clear on that up front) is a pain. Most folks have a second PC or laptop so they can get this started, but if they don't, this could be a show-stopper. Once It is up and running, though, it's a nice little printer. I suppose I wouldn't mind it having a physical Ethernet (Cat-5 plug in) connection so that wireless is never a worry, but that would likely add to cost (and HP offers other printers with that option).UPDATE 10/27/2011: Wanted to mention that the wireless reception in the printer appears to be decent. The printer is now in a far corner of my house (relative to wireless access points) and still prints fine from all devices. Also, setup on additional computers was an enterprise-class pleasure. Not sure why the SmartInstall availability (in web access) isn't on by default, but once I turned it on, downloading driver software to additional machines was easy. No need to run for the CD or over to HP's site, just download the software from the printer and then install it. That was a nice touch on what was already a five-star software experience (once initial setup was complete).I first installed the latest printer driver on my Mac from the HP web site, then plugged in the printer and powered it on. I hooked up the USB (a USB cable, supplied in the box, is required for initial setup) and the printer was not recognized by the Mac. So I power cycled and it was recognized.I ran the HP Firmware Upgrade Utility to flash the firmware so the printer will work with AirPrint devices like my iPad. The printer did not show up as a valid device. on the iPad Then I noticed that the blue wireless networking light on the printer was not on. So wireless would not work.I tried following the instructions by By R. Ruiz to add wireless networking, but they failed at the step9. Click the HTML CONFIG buttonThe web page would not display, so I could not proceed with the steps. This means I would be stuck using this as a USB printer, not wireless.Fortunately, I had a Windows 7 laptop. I plugged in a USB cable. Automatic setup did not work as advertised, so I inserted the driver CD and installed from there. I requested a wireless setup and did the steps manually just to be safe. It confirmed my SSID, and it asked for my network password. It then installed the driver and the blue light on the printer turned solid blue. I unplugged USB and printed a test page. It worked.Back to the Mac, I replaced its USB cable then went into Print & Scan preferences under Settings. The USB printer was defined there. But I wanted wireless. So I followed R. Ruiz's instructions again, and got past step 9. It turns out that wireless was already setup. This was confirmed by going to1) Click Open Print Queue2) Click on Open Printer Utility (this displayed the printer's web page)3) Click on the Networking tab4) Click on Wireless link on leftAt that point, I was able to confirm settings that had been established during the Windows 7 install.I then5) Clicked OK on the print queue window6) Closed the print queue7) Deleted the printer from the Print & Scan list by highlighting it and clicking the '-' button8) Clicked the '+' button and selected "Add other printer or scanner"9) Selected "HP LaserJet Professional P1102w" with Kind Bonjour and clicked AddThe printer was set up. I printed a test page from the Mac and it worked. I revisited the iPad and tried AirPrint, and the printer was displayed. I printed from the iPad and it worked, too. (AirPrint probably would have worked once wireless was set up on the Windows 7 machine.)So in summary...wireless setup did not really work on the Mac under Mac OS 10.7, it was only because I had a Windows machine that I could get it to work.Edit...later...I found a procedure that looks like it will allow you to set up wireless on a Mac running Mac OS 10.7. I will summarize it here:1) Power the printer on,2) Go to the Airport icon on the Mac's menu bar and click on it. Select the network associated with the HP printer.3) Go into Safari. Ignore the warning that you are not connected to the Internet. You aren't, instead you are connected to the web server on the printer4) From the Bookmarks menu, select Show All Bookmarks5) Under Collections, sélect Bonjour6) Double click the HP LaserJet Professional P1102w bookmark7) Click on the Networking tab8) Click on the Wireless link on the left hand side9) Select Infrastructure10) Under Network Name (SSID) click Refresh.11) Select your Network Name by highlighting it and clicking the << button12) Select your Security Mode. Enter your passphrase if you have one.13) Click on ApplyThe web page will disappear. At this point, go to the Airport icon in the menu bar and connect back to your wireless network.Proceed with Software Update (which, in theory, will install the latest printer driver). If that does not work, download and install the latest driver from the HP site.If the printer does not show up under Print & Scan preferences, add it as a Bonjour printer, as detailed above.This should take the Windows laptop out of the mix when installing wireless!Sometimes the printer seems to lose connection to the WiFi but for the most part is works great. I have had this printer for years and intend to keep it for a long time to come. It is compact, quick to start printing, and virtually never jams.A very nice, & compact wireless printer. Comes with an "introductory" toner cartridge which means it's only a fraction of a full cartridge, though we've been using the starter cartridge for 8 years.It has great quality. I used it for 10 years and it is still working.like it good machineServes me well. No need for color at all. Professional quality printing.
