Homebrew PCBs

Well done...

I guess you can't feed a pcb through?

you might try to tape a sheet of aluminium foil on a paper and run it 
through.
then you can inspect it under a microscope and you may also try to etch it 
(dunno
which etchants attack aluminium. - HCL does)

The fears i have are that either the drops leave space between them or
the layer is too thin to resist the etchant.
If that does not occur i see no further problems.

would be very nice to have high-dpi pcbs with so little effort.

Do you have a microscope to inspect the printout?
or would you rather just try etching....?

If that thing works you are definitely writing homebrew pcb history..

As said, sell a converted printer kit and get rich ;-)

Best luck, and i look very forward to further results.

Other thought: i read in the pc newspapers that the new inkjets use less 
ink on each
point, some very few picoliters, maybe best results are possible with 
older printers.
