has anyone tried this kind of ink refilling?
I went to get the Epson six pack in a hurry and they didn't have. But the guy in the shop told me to look this up.
Anyone with experience?

We do a lot of publicity posters and substitute cartridges don't last as long and block the jets. I suspect Epson s/w has a hand in this, the printer reports when the cartidge is not original. And may, or the cartridge may, report empty sooner than it should. Cost is a consideration, but the hassle of running-out of cartridges and getting supplies is also. And individual inks run-out out of phase anyway.

So advice on CISS ? - the link is geared to UK but I doubt it is administered from here.

TIA

link to system for one printer the site also seems to cover all Epson, and Cannon & other brands.

My printer is not cheap so I don't want to loose it. It prints on CD/DVD.
