Cost to print 5,000 B&W pages on my Brother laser: $25 ($12.50 per 2600-page generic toner).
Inkjets make no sense if you can put up the extra $50-100 up front for a laser printer. B&W is at least 10x cheaper, color is at least 5x cheaper, per page.
I have a Brother HL-2270DW for B&W printing, and an HP M251nw for color. Both are wireless, easy to set up.
Bonuses: Print 5 reams of paper before you need to swap a toner cartridge, instead of 3+ ink cartridges per ream. If you don't print anything for a few weeks, you won't need to throw out a dried out cartridge to use the printer again.
