Digital BW, The Print

>Is the R280 a current model?

It's the current version of the R260.  Look at the inks that are used to see
if the printers are the same.

>Also, will the R280's driver allow me to print "Black Only"

See http://www.paulroark.com/BW-Info/R260.htm   I assume you'll still need
to use QTR for Eboni black only.

>Would the R280 give me the same (or better) results I got with the 
>1280 and MIS Eboni carbon cartridge?

Far better.
