Homebrew PCBs

Many thanks to those that replied - all useful info and links.
I recently bought a new injet as a general printer Canon mp610. I 
thought i would see how well it would print out a PCB layout - i had 
some very old HP overhead transparency film on hand...results were 
better than the 
laser, crisp lines, dense blacks.  I produced 2 boards with them and 
they have turned out 100% - so might leave the laser for a while.
