[vox-tech] Printing photos with KDE

[Rod Roark]

OK my wife has a Canon i860 printer on a Slackware 10.0 box.
It's got a suitable CUPS printer driver installed and
everything works great.  Almost everything.

Now she wants to print (borderless) photos on 4x6 photo
paper.  The printer came with a holder/feeder for the paper,
but I don't know how to tell KDE or CUPS about the custom
paper size (there's a handful of paper size choices, but 4x6
is not one of them), and/or what a suitable printing utility
would be.

Does anyone know how this is done?

TIA,

-- Rod
