Is something not bad. Its only 25ppm(pages per minute) but its fine.
Has 2side print, which is useful.
Doesn't have builtin 2side scan which is a minus.
Have USB+network ports, also there is wireless model if you want.
Usually printers print faster on network than USB, because of protocols and because sometimes computers don't offer USB2 HI-SPEED, or they have hi-speed which is not activated in bios and/or provided on some USB ports.
You can see difference in USB ports from 10ppm to 20ppm, affects scanning too.
This printer is for 500-2000 pages per month.
Normal toners go for ~1500 copies, although there are some double toners i think they're called, that can last 2200 pages, according to their stats which was something like 7% coverage on page.
But you don't want those ( 2200 pages one ), if you don't have that much printing.

Lower class printer(cheaper option).
Doesn't have 2sided printing, and lower cartridge included at start ( 700 pages ).
Still can do 200-2000 pages per month on monthly base.
21 pages per minute.
Almost same models, have little difference(from my point of view).
How many pages do you scan per month ?
Usually I'm happy with HP, because they work almost out of the box.
On some older models, the software can drive you nuts, but oh well that's the life.
Can't offer you anything other, since @my company we mainly use HP.
Mainly higher class printers, because of the higher demands ( you know .. 55ppm print/scan, 8000-36000 pages per month and so on).
If there is someone that can say some nice models from Canon, would be good, to compare price/specs.
Usually HP provides all the software in their drivers ( Print+Scan Drivers + including Twain software to scan to - pdf,jpd,tif, send to email and some minor image correction on scan).
