I am waiting until I can find a old school (but small) desktop plotter, until then i have a lead on a epson R200, which with a (slightly pricey) kit or some homebrew spirit can print directly onto smallish size pcb's
;D
sorry no relevant information was given
[edit]if your looking for the name brand I am not having much better luck, course here is a 7$ generic
