Toby Marshall (kymarto) had quite a lot of information about printers that he was sharing a while ago. Perhaps you could ask him. My problem with inkjet printers is that the inks tend to dry up on me before they can be used up so I only ever get a few prints before I have to replace a $30 cartridge :( I also think that you need to be using very white paper. Remember that fractals are naturally backlit!

Fractals will always amaze me!
