Go to walmart.com, find 5 printers you like/need. Google about their support in linux (i bet at least one of 5 will be very well supported, if no - repeat first step.) and order it. Done. While you shopping I would advise you to look also for price for their supplies and ability to refill cartridges. While it is not necessary for you to refill these, the fact they are refillable will put a pressure on the price on retail market for supplies for this printer, which make it more cost effective for your. In general I found older HP business laser printers and Brother printers are quite good in this regard.
