Homebrew PCBs

i finally got around to using soidium silicate(water glass)on a small 
piece of pcb. i hardened it with co2(carbon dioxide), then etched 
with ferric chloride?(sp).i used a tooth pick and put some small 
dots,large dot and a line of water glass on the board, then hardened 
and etched, it came out excelant.i noticed a very small dot that i 
put on there, it was about .005 of an inch. NOW -if i can gat an 
inkjet printer to handle the water glass and a streight through feed 
for the pcb i will be in business.
if any one has any suggestion on what printer to use i would 
appreceiate it.i dont know which would be best-a pezeio or heated ink 
head. the water glass has some water in it. JUST LOOKIN FOR SOME 
THOUGHTS FROM OTHERS.
