Most of the printers I got hold of had been aquired BEFORE I found out about QTR, so what you say is actually not correct. I would not have bought a new 1430 without having any reason to do so. It's also easy to say that in hindsight. I was looking for printers known to have good print density (like the SC3000) or the older ones which had the Backlight Film setting which prints more densely. All the printers I bought were falsely advertised as working but out of ink in one of the cartridges. I would never have thought one printer after the other would have blocked nozzles that I couldn't clear. Perhaps the sellers were not deliberately misleading me. I've noticed many understand nothing about inkjets and the effects of running out of ink and long term storage. The printer may have worked perfect the last time they used it.
If I had known about QTR before getting the very first printer, I would have only paid about $30 because I now know how to use ANY cartridge on its own and make it print with lots of ink. I've got a couple of R210 printers now which I'm in the process of trying to clear blocked nozzles. If I can't unblock all of the colours then I can just use any cartridge whos nozzles are all clear.
I've also gained a huge amount of knowledge of inkjets, their mechanisms, ink types, storage precautions (I'm not making a circuit board every day), maintenance, advanced head unblocking methods, etc, etc. I could have bought a 1430, had it stored for some time before the next use, then found out my new printer has blocked nozzles.
So I'm not doing too bad for my $200+. Now that I know about using ANY one cartridge, I've got three printers that work with QTR, and like I say the knowledge I have gained is something I treasure and is worth money by itself, and can save me money down the track.
