First off, the only reason to have an inkjet is for photo printing. But the consumables are rediculous, so only get one if you can get third party ink at reasonable prices. Also plan on printing something at least once or twice a month, or the heads will clog, necessitating wasting even more ink! I'll just print out a cute picture or webcomic to put up the fridge if I have nothing else. And I may not bother buying a new one in the future... but I have an old epson 6-color (CMYKcm) printer that's almost 10 years old and still works great (as long as you don't let the heads dry out)... which also takes super-cheap generic ink. Newer ones can have issues with DRM chips in the ink cartridges which can make it harder to get generics sometimes. YMMV. But it costs me less to print a full page photo on cheap glossy-photo or matte paper, then it would to order it online, so I've stuck with it.
But for any normal printing (i.e. NON-PHOTO), you're going to want to use laser printers exclusively. Their more durable, much much much faster (a 8x11 photo in hi quality on the ink jet takes something akin to 12 minutes to print)... on a laser, everything is blindingly fast.
You also definitely want to find a laser printer with cheap non-OEM toner that's readily available. I have two laser printers for day-to-day printing, a cheap ass low-end 600dpi brother (which is perfect for text buisness documents, word processing, printing the ocassional groupon or amazon return lable, etc) and generic replacement toner is dirt cheap. Even the drums are very reasonably priced. Use this for standard monochrome documents (comes out to under $0.01 a page (not including paper, and assuming %5 coverage, standard text documents, not solid black, etc))
I also have a nice office color laser (full duplex is a bonus in these larger higher-capacity office printers). There a lot of options here, look for a refurbished one online. (Also verify you can get generic toner) Mine was $300 and comes to about ~$0.06 a page.
