Not used Permajet, but when I did home printing I used Fotospeed inks available from RK Photographic in Potters Bar. Also used Lyson ink but my inkjet printer gave up before I'd used them up and I never went for the home printing route after that. But Fotospeed were excellent if you download their colour profiles.
What printer do you use?.....or more to the point....pigment or dye inks? By the way...what sellers charge often bears little relationship to the quality. I know one well known supplier who markets two reputable brands (at very different prices) but has admitted via an email exchange that the inks are exactly the same formulation but from different places. I am a fan of German OCP inks myself.....with my Canon9000pro I calculated, by refilling my original Canon carts when needed, my ink costs are about 10% of using OEM inks.
I also have the R2880 so the same inkset. I still use OEM carts but not for long...I am about to try a couple of refillable carts and ink supplied by Octoinkjet which I believe is manufactured in America. One option I considered was buying 220ml Epson carts and decanting the ink...people do this....but decided to try the Octoinkjet stuff as the ink company website gave me confidence. As I recall there are refillable carts available for the R3880. As it happens, I have been watching s/h 4880s on eBay...often a lot cheaper than the R3880...lot bigger unfortunately.
I don't know much about the R3880 to be honest...but my R2880 was bought s/h in mint condition for well under half the cost of new (still had the first set of carts in it) and it still looks mint and I could probably sell it for much more than I paid. It works perfectly and I would definitely buy another modern printer s/h under the right circumstances.
As for the Permajet carts......even if they are the ones you prefer it might pay you to consider other inks.
And....are you going to need carts that large? That amount of ink represents a lot of printing....which means a lot of paper as well. As it happens, I am in the process of trying a new paper from Permajet, something they are selling as a replacement for Ilford Pearl. They claim it is as good...it isn't.
I have a used set of these carts and some spare ink that you are welcome to if you want to drive to me and collect. Theyve not been used for around 3yrs but were fine at the time. Btw they fit the 3800.CCPNot sure if we are talking about the same printer, when you mention R3880. The one I am talking about is the Stylus Pro 3880. The advantage of having these big carts is that you can refill without removing the carts. But it's interesting what you say about the paper, not being as good. That's the thing, even the though I feel I should be able to trust a well known company like that, that may be the case with their ink, as well as the paper you mention. But yes, I will consider other inks to fill their carts. Back to the subject of the printer it's self, so many times I have bought secondhand stuff, and been unlucky. Things that can't go wrong, I do buy secondhand, but I personally won't risk a secondhand printer. I know my luck.
Google both names and you will come up with the same printer...I think I use the short version. I think my R2880 has a longer name as well... The Permajet paper isn't bad but print the same image on the Ilford paper and hold them side by side and the Ilford is clearly better in my eyes. Permajet claim their paper works with the same profile as Ilford...it doesn't. Although to be fair....if you use their paper they will make a profile for you for free. Must get round to making use of that offer sometime soon!! To be doubly fair...once I have done this the prints using Permajet paper might improve. Just one point about not removing carts from a printer.....I did read that carts using pigment ink had to be agitated on a regular basis to stop the pigment settling. Might be worth researching this. When I used a CIS with my R1800 and before that the Photo stylus 2100 (both pigment printers) I gave the ink bottles a bit of a swirl every week or so because of this. I remember reading that people who complained about CIS units clogging printer heads might not be doing this and so the nozzles were eventually clogged as the ink became thicker and thicker. But I did read all this years ago and have forgotten the finer details....
