I echo exactly what Zepper says------even though bottom end inkjet printer can be had for as little as $30., the total cost of ownership over a one year, two, year, or longer interval will be far less is you select a more expensive printer that can use cheaper but equally good third party cartridges. Or readily support very easy refilling.
When you consider the very desirable Canon ip3000, in my humble opinion as the best choice for you, can be had for as little as $80. with some creative shopping, I just urge anyone to really investigate the inkjet printer market before they buy. Steves digicams and the nifty stuff forums are good places to find information on good consumer choices. -------------but the bottom line is the more you print the more important making good choices are.
But when you consider that even one set of replacement OEM cartridges can easily exceed $50., its not hard to understadn that old adage---You can pay me now or pay me later---with the later being the really unpleasant option.
