Until a recent office move, I was connected to a HP P2055 laserjet printer for my heavy duty and black and white printing needs. We have had this printer for about a year (this has caused some office debate with votes coming in for "6-7 months" to "about two years") and at times it has had up to five of us using it on a daily basis, although currently there are just three people. Visually it is a chunky thing - light grey on the top, front and left and dark grey below, to the right side and at the back. It is quite heavy to lift - in fact I can barely lift it - but I don't think you buy laser printers for their portability or aesthetic reasons. Dimensions are approximately 35cm square at the front with a depth of about 27cm.
We are connected to it via a network, and I cannot say how straightforward this was as I didn't do this myself, but it certainly works fine and I can still print to it even though I have moved and am based on a different floor and use a different printer as my default printer now (I like to do this sometimes late on a Friday afternoon when there is only one person in the other office and it makes her jump). As a laserjet it only prints in black but quality is good - I am completely satisfied with any Excel or Word documents I have printed, and certainly my colleagues are happy with printouts of invoices and statements from the database. Occasionally I have accidentally sent coloured images to this printer instead of to the colour inkjet printer and although it comes out in shades of grey, the quality is still good and edges are clear and sharp.
Print speed is good, certainly a single page or short document is printed before you have even got out of your chair usually (sadly no one has worked out a way for the page to land on my desk without me having to move). There is a little plastic 'stopper' that flips up to catch pages but this isn't really necessary. Although it prints fast, printing is steady and controlled; it doesn't throw your pages violently out across the floor like some inkjets do. We only use it sometimes when printing larger print runs, but it seems to be a case of personal preference rather than necessity.
At certain times we can print up to 700 pages a week with this printer and we have had no jams or other problems (although large print runs obviously do take up more time than just a few pages, so occasionally I have to be patient). The printer holds about 250 sheets (half a pack) in its single drawer, but we try not to overfill it. There is an indicator on the outside - a little plastic guide as to how far down the paper is.
The printer is fairly quiet. When it is on standby you wouldn't know it was there, it whirrs when something first gets sent to print but in a busy office this is barely noticeable (unless you are on your own and it is quiet, then it is loud enough to break the silence) and hums quietly to itself during a larger print run. The noisiest part is probably the paper feeder when it gets low. Again this not something you notice unless you are listening for it or it is particularly quiet. A little light flashes when paper is out or the toner gets low.
It can do two-sided printing but this isn't something I need to use personally. The printer is usually used only for A4 paper, but I think smaller paper sizes and envelopes can be used as there are plastic adjusters in the paper-tray but I have never tried this. As there is only one tray you would only be able to have the one size of paper in at any one time, which is a consideration if many people are using it. We do often print labels on it using the Avery system and this is no problem at all.
Overall I recommend this as a good printer for the office environment. If lots of large print runs are done by many people then you may want a higher spec machine which is faster or an additional machine, but for the average office I suspect this would be more than adequate as it has been quick and reliable in my experience and has met our expectations
I can't tell you when we last changed the toner - I wouldn't like to hazard a guess but it must be a long time, as I believe it lasts for 6500-7000 sheets.
