I am looking to get a new prnter after going through a few Samsung CLX3185.  It has been nothing but trouble and does not seem to last.  I do enough prints to get a printer similar and was looking at some HP printers as I have used them in the past and they just seem to print for ever without issues.

What I am after is something like the Samsung but really want something that is going to last I would say maybe about 100 pages per day is so needs to be able to do the job without braking down all the time. 
I am also after a printer that is not to expensive to run the samsung does seem to cost a bit to run and to fit some of the parts like the fuser unit is a bit tricky. 
I like the Corporate HP Line of Printers, although some models are not user serviceable friendly to replace fuser unit and other parts that are contained within maintenance kits. If you are like me and like to be able to service your own printer vs having to bring it to a genuine HP service center, I'd look at a printer model of choice and then perform research on the model and look for a maintenance kit for it and its cost and see if you can find a PDF that shows the installation PROCEDURE. Also CHECK into toner cost and print yield per cartridge. I would avoid the cheaper HP printer line and go towards a more rugged model with 100 pages printed per day. HP also has a good warranty as well as offer extended warranty plans. A client of mine actually leases the expensive printers from HP and if the printer craps out after 5 months, they have to replace it immediately. ONE of the printers they are paying $20 a month LEASE on.Is this a question or a promotion?
Everybody is welcome here, but if you are trying to SELL something, you will get a deaf ear. You already have said HP  all-in-one.
Now here are some others in alphabetical order.
Canon Pixma MX350,
 Epson WorkForce 610,
Lexmark Prospect Pro205.

For high end business class printers, try Konica Minolta.

Now, what was the question?
