I've had an hp LaserJet 1320 for a while at home. My dad bought it after we got tired of our Lexmark 5700 coughing up ink cartridges after they were only half empty.
Physically, the 1320 looks like most laser printers, with only a slightly "curvier" look than most. We also looked at the hp LaserJet 1012, which is their cheapest model, but decided to get the 1320 instead because the 1012's chassis is shaped more like an ink jet, which is ugly, and leaves it underendowed in the paper tray department. (It has a very small tray, and unlike most laser printers, the tray isn't enclosed inside the printer; it just sticks out.) The 1320 also has a few more indicators and two buttons, which makes it easier to operate.
Since it's an hp printer, it is compatible with Windows, Mac OS X, and Linux. (Seriously. See my experience with Linux and hp tech support. They actually fixed my problem.) It's usually plugged in to our Mac, but I'm considering plugging it into my server instead, because the Mac has trouble sharing printers.
The first thing that I noticed when using this printer is the insane speed. It runs at 22 pages per minute, which is amazing when you first see it. Granted, I've come from an ink jet, and the speed isn't that great compared to hp's business models (our LaserJet 2420dn at school does 30 pages per minute), but 22 pages a minute is less than 3 seconds between pages, and the startup time is less than 8 seconds. In short, if you're used to printing text documents on an ink jet, you will be blown away.
The text quality is, as far as I can tell without running formal tests, crisp and pretty. The image quality is fairly good, for a laser printer. Since it's black and white, you won't be using it to print photos, but it won't make a mess of pictures or diagrams in documents you print.
I can't comment yet on the price of toner cartridges for this printer, since we haven't had to buy a single cartridge yet. It's almost two years old, and we've only used two thirds of the first cartridge, which is a normal one, not a high-capacity one (which would last 2.5x longer).
The only flaw with this printer is the manual feed. Essentially, the distance between the manual feed roller and the sensor that triggers the printer to pull the paper in is too large, and the rollers only spin a small distance. You have to quickly and correctly insert the paper, or it will either feed crookedly or not grab the paper. Even with this flaw, it's still pretty easy to feed envelopes and such.
Since I don't have the networked model, I can't directly comment on the networking abilities of this printer, but if our LaserJet 2420dn at school is similar in any way, the networking will probably be quite good. The 2420dn even has the ability to send status messages to a syslog server on the network, so you could (theoretically) have the computer read the log message and email someone when a paper jam goes unfixed for too long.
As far as I can say, this is a great, reasonably priced printer that prints high quality text output at a brisk pace, and does a decent job with graphics too.
Update: After 2 years, I finally replaced the toner cartridge! Hopefully I won't need another for a few more years. ;-)
