Priniting with cups, no black!

[Rob Brown-Bayliss]

Hi, I have installed an epson c61 printer, and am using cups on the
local machine.

If I preing a cups or a postscript test page from the gnome printer
administration app, it works fine.

But when I print from within a gnome app (ie gedit or gunmeric) all
the coloured text comes out, including shades of gray, but anything
that is solid black comes out white (that is it is not printed).

Any ideas as  to what is going on?  I even went an brought new ink
cartridges this morning but get the same result.
