I have not had success with similar printers, because the printout would  
never come out good enough (lines etc.).
That's why i feel that resolution/nozzle count may be a factor, as well as  
variable droplet volume capability.
I must admit however that i did not employ the curing procedures i used  
for successful c84 prints, so it may be possible to use one of the older  
printers and i just did something else wrong. Also, i did not have  
spongeless carts for the old printer and the refilling was a nightmare  
wasting lotsa ink by drainage.
You can see one of the first test prints with staedtler red ink here:

Before that i tried a HP with acrylic floor polish, total disaster!


Short story is all 4 printers i tried before the C84 were a total flop,  
two of them so bad that i was sure it was impossible to do (before Volkan  
came along having done the impossible!). I'd like to know if they would  
have worked somehow, but i'm not prepared to go there again myself ;-)

I'm still curious where this future floor polish thing came from. It may  
be that someone actually got inkjet PCBs to work years before the recent  
successes, but nobody seems to know anything more about it.

Anyway, enough of the old failures, we have something now that works, on  
which we can build on.
The more people working on it, the better!
