Homebrew PCBs

Hi folks I am new at this and as I have a Epson R300 printer which 
allows printing on CD it should be possible with the correct driver 
to print a PCB up to the size of a CD (120mm) diameter. 

Now I am sure I am not the only person to have considered this but 
unfortunately my programming expertise precludes me from even 
attempting it! 

The black ink cartridge could be filled with resist instead of 
normal ink and providing that a flusher solvent was available for 
use at the end of each print run the printer should come to no harm 
either. A CD is a similar thickness to a PCB so a very 
accurate "print" would be obtained directly onto the PCB.

Have any of you clever guys out there done any work on this front??

Look forward to some replies telling it has all been done and 
telling me where to download the necessary software!!

Best regards,

Bryce
