[cups.bugs] can't access local printer in Cups 1.3.10/gimp 2.6.7/firefox 3.6.13

[doug]

I'm running linux Mandriva 2009.1 on a 64-bit PC with Epson 
Stylus Photo 2100 printer.

With the printer attached to the 64-bit PC locally, I cannot 
print from firefox or gimp, but I *can* print from 
OpenOffice or a text editor.

On the other hand I can print from those apps on a *32-bit* 
PC with the printer attached locally.

Where's the error?
