I have had wonderful results with two Samsung desktop laser printers
ML 1710 Laser
SCX-4x21 Laser ("x" is some number)
ML is a printer-only. Bought for less than $100. My wife tried to wear it out, replacing the toner 3 or 4 times. Thousands of pages printed. Printer is still alive & operable, just needs a new toner, as it has become superfluous since we bought..
SCX-*, which is one of those multi-function jobbies: print, copy, scan, fax. Bought for less than $200. Only replaced toner once, so far, but it has been a rock.
Drivers for both are great and they are easy to operate. Also, they come with linux drivers.
BTW, my wife is in school and prints out all her lecture slides & notes.
