What type of printer do I need to transfer photos made on my phone?

I don't know how to transfer the pictures I make with my T Mobil Prepaid cell phone. What kind of printer does it take %26amp; how is it done?|||I wouldn't think you could transfer them to a printer, you have to transfer them to a PC, then print from there. I know some cameras have a stand-alone printing docks, where you don't need a PC, but I don't think that this is available for phones yet
