Homebrew PCBs

I intend to buy a inkjet printer and I have 2 options: CanonIP1500 and 
HP DJ3940.
Both printer have 4800x1200 color resolution but Canon have only 
600x600 black and white resolution (HP have 1200x1200 rendered B/W 
resolution).I read some rewiews about those models and the "winner" 
(in photo quality terms)is Canon.  
So I'm confused...It's OK 600x600 or should I choose the HP?

FWIW, my old Epson Stylus Photo 870 gives 1440 x 720 dpi resolution in B&W. 
I get *very* good results with it.

I found 600x600 to be sufficient, underetching is probably getting you  
earlier here than resolution does.
However, if i could choose, i would take a 1200dpi printer. Mine was  
advertised as 1200, but it is "fake" dpi.

This "fake" dpi confused me. In my knowledge, the real resolution 
depends on factors like ink and paper. For example, if I use a porous 
paper, all lines will be deformed. The ink dot will be larger because 
of paper absortion.
I forgot to mention that I use an "original" transfer method whith 
combine both TT and foto method. I print on normal paper whith inkjet 
printer (at home)and than copy this print whith a Xerox on transfer 
paper (at work).

What i mean is the 1200x1200 stated was in reality some "image  
enhancement" mumbo jumbo. For photos the resolution is supposed to be  
equivalent to a 1200dpi printer. Me thinks the only thing equivalent is  
the text 1200dpi on the box.

The real resolution is 600dpi, that's also mentioned somewhere in the back  
of the manual printed so small you first think it is only a line dividing  
the other "features".

Of course you are right, not only the dpi count, also ink or toner and  
paper makes often much more of a difference. With lasers the really high  
resolutions often claim to have a special fine toner, not sure if real.

What i do know is the LJIIID with 300dpi was not good enough to make 0.5mm  
pitch smd, 600DPI is.

In HP advertisment they say "Print quality-black, best quality: Up to 
1200-rendered dpi black" witch seems to be some image enhancement

Canon's 600x600 seems to be fair, more credible...I hope...
