5 out of 5 eggsRetail Paint Store Printers

Pros: These are the workhorses of the printer industry. The setup was simple as in networking them and using them. They churn out invoices day after day flawlessly.

Cons: None

5 out of 5 eggsExcellent printer!

Pros: If you need a monochrome printer for small to mid size business I recommend this one. I had 3 of these in my previous office and they were still operating strong after 4 years when I left. Because of that when I opened my new office I bought 2 and when the Brother that was here before runs out of ink I won't be buying the cartridge and drum I will buy another HP 401.

Cons: It wasn't free.

Other Thoughts: Not sure about those on the market right now but the OEM that came with this printer hit at least 4k pages. Really surprised me. I mostly print forms, documents and letters.

4 out of 5 eggsGood small laser printer

Pros: We have 5-10 of these at various places. They are great for home office type locations and the quality is quite good. The print speed is great.

Cons: Be sure to order a USB printer cable.

5 out of 5 eggsOne of my favorite HP printers!

Pros: We have several of these printers and they have been nothing short of a godsend.

Cons: I can't think of any cons.

Other Thoughts: I would recommend this printer to anyone looking for a personal printer that is extremely reliable and greatly priced

4 out of 5 eggsDecent Network B/W Printer

Pros: Quick Warm Up, comes with full toner cartridge not a tester like most, displays IP on LCD read out, easy setup and gives you the option to be IT managed so more options are at your finger tips. Bypass Tray is in front not rear of printer (which is good and bad)

Cons: Bypass tray in front (can make placement a bit of a chore for close quarters)
Sorta big and unruly for my likings in comparison to competitors
Bypass try doesn't always sense certain paper weights, our CFO had to put their old Laserjet 1300 back into service because the bypass couldn't sense the checks were in the tray and ready to go. HP lost an Egg for this, sorry guys - love your printers but this is what the bypass is for.

Other Thoughts: Overall I would not hesitate to recommend this to anyone. If you need a good and reliable b/w printer this is your guy!

4 out of 5 eggsGood

Pros: - Good print quality, fast.

Cons: - Couldn't get it to work over USB. I installed it just over a year ago so I don't remember details but it just wouldn't work. I ended up having to plug it into my network and set it up on a Windows print server. Client computer is a Windows 7 32 bit.... same drivers, just USB wouldn't work.

2 out of 5 eggsTerrible drivers

Pros: When it works, it prints fast, as expected for an HP laser printer.

Cons: The drivers are horrible. I've sold three of these printers, two purchased at the same time, another recently purchased, at least 6 months apart and all have had the same issue. It starts out fine until it loses connectivity. This issue has occurred on Windows XP (32-bit), Vista(32-bit) and 7 (64-bit) locally connected via USB and on completely different networks in different geographic locations. Jobs get stuck in the queue and the machines have to be forcibly rebooted (spool service won't close, manual machine reset required) in order for the jobs to print. I tried updating the firmware, which states it is addressing these issues with only short-term success. I ended up having to uninstall the drivers and download the HP Universal drivers from the website in order for the issues to go away.

Other Thoughts: HP's corporate laser printers are still the best, but their "workgroup" and home-line printers have gone down hill over the past 10 years. These issues should not be present with any printer, especially one labeled "Pro". If HP can't produce a small printer without issues right out of the box at what they feel to be a "competitive price", then produce one without issues at a price that makes it profitable. People will buy what works; ruining a manufacturer's reputation over a price point will cause consumers and resellers to look elsewhere for their needs.

5 out of 5 eggsI'm confused...

Pros: For me, this has proven to be a great printer. It is inexpensive when compared to my first HP LaserJet II, or my LaserJet 4 that I've had for probably 15 years and is used daily and abundantly. The last time I ran a printout, it showed over 150,000 pages and all I have ever done, is use HP toner only, keep it clean and away from people that walk around with cups of coffee that end up spilling them into the printers as they do on their keyboards.

Cons: None thus far. I purchased this printer within weeks of HP putting it on the market as it reminded me of my faithful LaserJet 4. Will it last that long?

Other Thoughts: I've been operating my business from before the "cat's meow" was having an Epson DOT Matrix (This will throw a previous reviewer for a loop that, although claims to be of average technical expertise, did not know what "monochrome" meant and purchased the printer in any case. Now, is this lack of technical expertise, or an issue with the English language?). Over the years, I have purchased a number of HP printer of differing ilks, and I cannot ever remember one of them breaking other than from endless use and a finite reasonable life. I only made sure that whether toner cartridges or ink, that they were legitimate HP product and kept them clean (An occasional use of an air can does wonders). I am certain no one cares about reading my opinion as to why they may have had any issues, and I am not interested in even going there. I will, however, say this much; in my lengthy experience with HP printers, should I ever need a printer, I will assess my needs and buy an HP intended to meet them. I am certain there are other great brands out there, but for me there is only one way to go. Whether the 400 will last as long as my 4, I do not know. But I am confident it will serve me well through its useful life and longer than intended. Incidentally, I do not work for HP nor do I have any affiliation with them. My business is concrete.

5 out of 5 eggsGreat Cost Per Page and Speed

Pros: This printer can be had from big box stores for $200. Generic high-capacity (6900 pages) toner cartridges can be had for $20 in bulk. I got twelve of these for my employer to test as a "disposable" printer and they've been rock-solid after finding good generic toner (the ISO9001 cert seems to do the trick). For under $50, you can get an HP 3 year Care Pack, which gives you next business day exchange and shipping is included. That's four years of printer service after adding on the initial one year warranty. I don't know how well the exchange service works because we haven't had to use it yet even though we've been beating on a dozen of these for months now.

Cons: This printer does not make coffee.

Other Thoughts: This is definitely a no-brainer for nearly all office printing needs - cheap enough to hand out like candy. Durable enough to set it and forget it. I just bought another 10.

5 out of 5 eggsGreat printer

Pros: Great printer for single office use. Prints fast and clear, network works great.

Cons: I would not use this printer to share between multiple users, works great for personal laserjet

Other Thoughts: Toner cartridges cost just about as much as the printer
