r2880 with a fotospeed CIS
we have a 3880 pro a 4880 pro and a 9880 pro.
all awesome printers (the 3880 is the A3) whcih have never given us any bother.
we have looked at bulk systems, but havent got around to buying one.
I've got an R2400 which is great and the R2880 is a bit better. I also use the fotospeed CIS system without any problems.
but I use refillable cartridges.
