Strengths: Solid performer, quick, very good quality copies

Weaknesses: Could be less flimsy in the construction department.

Summary: This unit is great for the home owner who wants a solid All in one machine that is a solid performer. It prints clear, scans are above average and it runs quite.

Strengths:

Weaknesses:

Summary: I have had the 7780 for about a month now and have been very pleased with its performance as an all in one. It meets the needs of my home office very well. While it is not a panacea, as nothing ever evented will be, it comes close. A little pricey, but worth it. Go for it.

Strengths: Not complicated. Works fast and effortless.

Weaknesses: Noisy

Summary: Relatively easy to assemble and connect wires. Painless to install software. Everything works fine as expected from HP. Network setting was also uncomplicated. Stable; do not jerk around when printing. Double sided printing is a great help. Scans document really fast. Fax works without surprises. Installed memory card reader saves me a lot of time. Colors are brilliant. Prints quality is superior. Looks great! The worst that happened: I could not find a slot to insert envelope. Resolution is just insert it on the top of paper stock in the tray. No special attention required.

Strengths: Hardware setup was straight forward.

Weaknesses: Unable to install workstation software.

Summary: The software installation was performed 7 times on 4 different XP PC's both with and without HP Tech Support. Each Installation resulted in a different error for each PC. HP Tech Support came in remotely and did an installation and got the same error. They then said it was a bad Software CD and had me download 300 meg of new software which when used resulted in exactly the same errors. At this point we had spent more on the installation than the printer cost. We returned the printer.

Strengths: Fast and feature filled

Weaknesses: Pricey, ADF, footprint

Summary: This printer is the best one that i have ever owned. You can scan to your computer or even a memory device. Photo quality is excellent. ADF could be better. Printer has a big footprint so you need a lot of room on your desk.

Strengths: it works

Weaknesses: no fax receipt w/ content

Summary: I've had the unit for 3 months. Two complaints (everything else is ok by me). 1. The fax machine can print a receipt but it can not print a receipt that shows a portion of the faxed document. It only shows the date, time, pages and phone number. Not the fax's content or a portion thereof. Hence, you have NO WAY of proving the content of a fax. After decades of fax machines being around, how a company can not include this is beyond me. If you need to prove anything was ever faxed DO NOT PURCHASE THIS. IN FACT, THIS MAY BE A PROBLEM WITH THE WHOLE LINE. MAKE SURE YOU CHECK! Second, it's loud when printing....Everything else has been what I expected.

Strengths: Copies, faxes, Prints, Scans

Weaknesses: Tractor feeder.

Summary: When item was first received, the product seemed to have difficulty with regards to the tractor feed so the item had to be returned for a replacement. The tractor appears to be the weakest part of the machine. If you feed more than 5 pages, one of those pages will eventually piggy back off another. Also, there is a risk of damaging the document if it is not perfectly lined up on the feeder, I've had a few originals eatten. The software installation won't install the scanner and after contacting customer support it appears that I'll need to do some registry editing so that I can do a fresh install. Simply removing it from the control panel doesn't clean everything up.

Strengths: Well featured All in One printer.Junk Fax Blocker.High volume paper storage.

Weaknesses: Significant "out of the box" assembly.Front panel assembly can result in switch buttons becoming trapped.Takes about 10 minutes to go through its power up routine.

Summary: In general I am very happy with HP Officejet Pro L7780. When I initially assembled it out of the box, attaching the front panel plate resulted in one of the switch buttons becoming trapped and therefore mis-operation - it took me about 30 minutes to find the cause. The printer is fast and economical (the cost of genuine HP ink is reasonable). One irritation is the time it takes (each time) the printer is powered up to go through its test routine - about 10 minutes. In the 2 months that I have had the printer it has locked up 3 times, requiring a power reset. Also twice during a print run, it interrupted the print run to carry out some kind of internal test ( about 5 minutes).The junk fax blocker is excellent.

Strengths: Great on XP and Win 2000

Weaknesses: Poor support for Vista 64 bit and Office(Word 2007)

Summary: Had to return my L7780 having tried a service spare. Both worked fine on XP and 2000 and even Win 98 (hard wired). But with Vista the supplied drivers

Strengths: Easy to use scanning software

Weaknesses: Tech support sucks unless you can speak Indian.Not VISTA 64bit compatable out of the box.

Summary: I spent 4 days trying to get this machine to work with an HP Vista-64 bit machine. All you get is one Indian after another who can't speak or understand English. I gues that is to be suspected as their phone systen does not work well either. The ink cartridges all blew up after 12 copies. The document feeder is cheency. Bottom line it went back to HP along with the computer.

Strengths: It looks nice in the Box and thats where it should stay

Weaknesses: Software doesn't work on Mac or XP and support is from India by e-mail at best!

Summary: It is apparent that the HP All-In-One should be recalled! Software out of the Box has major fatal errors on XP with no support at all from HP (India HA!) Tried to load on my new MAC software issues loading but HP new about this! Best suggestion is don't buy! My unit is one day old and I am returning it back to the store. (Techincal support by e-mail is not at all Support!)

Strengths: Fully loaded printer with all imaginable features.

Weaknesses: Just a couple

Summary: Overall, I can enthusiastically recommend the HP OfficeJet L7780 All-In-One printer, fax, scanner, copier. It's super fast, the print quality is excellent, and economical to operate. According HP it'll cost about 1.5 cents for a black page and around 6 cents for color pages, depending on the complexity. The direct photo printing capabilities are great for both office and home user, and if you do a lot of printing, or if you need to print two-sided copies then this is a fabulous machine. The wireless capability and digital filing are just the icing on the cake for me. On the other hand, there are some potential drawbacks. The photo menu is not always intuitive, and some of the options could be re-arranged to fix this. I've also once experienced a false alarm paper jam when doing a large print job. For instance, one time while a large document was printing, after the first 7 pages or so, the machine stopped printing and said that the printer had a jam. So I checked to see where it was and there was nothing to be found that could have caused a jam. So then I had to restart the job and everything went smooth from then on. Hopefully, I never got this false alarm ever again.This machine is great and I highly recommend it.

Strengths: clear intuitive directions; multiple options; clarity of printing output

Weaknesses: none noted; performs up to expectations

Summary: excellent all-in-one device, far more sophisticated than earlier versions; performs all functions with intuitive directions; output looks at times laser-like, rather than ink; good value for price point

Strengths: NEVER GOT A CHANCE TO USE IT.

Weaknesses: DOES NOT HOOK UP TO A WIRELESS ROUTER

Summary: I purchased this printer because I was told that it was designed for a high volume office. I was also told by a Staples employee that this was the best printer they had. I am now on my 4th printer in one week. The first 3 printers froze up when I tried to connect the wireless up. The 4th is a different printer all together. I later found out by troubleshooting the problem that this has happened to most of these printers and hp knows about it and is still selling them. HP tech support told us to update our router firmware, which we did...still nothing. Please spare yourself the trouble that I went through and don't buy from a company that knowingly sells a product that is inoperable. The following is straight from HP's web site.HP Officejet Pro L7500, L7600, and L7700 All-in-One Series - The HP All-in-One Stops Responding during Wireless Network SetupIssueThe HP All-in-One turns unresponsive during the wireless local area network (LAN) setup. No buttons on the front panel respond, and the HP All-in-One cannot be turned off with the Power button. The control panel display freezes.

Strengths: nice print qualityone of the best cost per page for an inkjet

Weaknesses: does not work reliabily, incompatible with MS Office 2007 (cuts off end of MS Word documents and forgets to print first columns in MS Excel spreadsheets)

Summary: HP customer assistance tries their best but the drivers for this printer are defective. It just does not work reliably. As best I can tell this printer is incompatible with MS Office 2007 (cuts off end of MS Word documents and forgets to print first columns in MS Excel spreadsheets). ONE of the LEVEL 2 tech support folks confirmed this. I have spent hours upon hours trying to make this thing work reliably without success. Periodically it just decides to stop working. Save yourself the headaches. While this is suppose to be a fully network capable AIO it just does not work that way. When I have network problems Hp blames it on everything except their printer. I have installed/uninstalled the drivers for this thing dozens of times. By the way, you don't just uninstall. You have to go in and do some editing to get all of its bits an pieces out of your system. Great potential, poor delivery
