I'm new to this list, and maybe my question has been posted before.
Briefly,
a) Does Epson R285 printer use the same inksets as the R260-R280?
b) Is Epson R285 compatible with MIS RCC-T0771-K cartridge for carbon
B&W printing?
b) with all this court storm, will be the MIS carbon cartridges
available in Europe in the foreseeable future?

Thanks a lot,
Juan Riera
