The R1900 is physically virtually identical to the R2880, other than it uses a different OEM inkset, doesn't have a front sheet feed option, and has the silver and black trim in a different arrangement. So whatever works on the R2880 should work in the R1900. The only catch is working out the ink placement correspondence, given the different OEM inksets. The R2000 is a minor upgrade of the R1900, and so the same comments apply. (I have all three printers.)
