Homebrew PCBs

I had chance to make a trial with old HP930C. I refilled black
cartridge with MIS-Pro MP-4-PK Photo Black Ink. After a few try I got
comparable results to Epson. I could not able to upload results to our
folders sorry for that. I think, I need moderator's power. So here is
the configuration that I used,
Under Setup Menu:
  -Print Quality: Best
  -Paper Type: Plain Paper
Under Advanced Menu:
  -Print In Gray Scale 
  -Black Only
Ink Volume:
  Light
Dry Time:
  select two bar right from the center

Note: I pre-coat the board with very thin layer of brake fluid but I
don't think that it is necessary.

From this early test, it seems we can also consider HP printers. In
this test I could not able to use best settings of the printer because
of the black ink. 
Again,  we need more people to  be involved in direct inkjet printing.
