[gentoo-user] can't print from firefox, but CUPS says OK

[Allan Gottlieb]

For some reason printing from firefox has stopped working.
When I ^P or file-->print and select a printer (there are two),
the "print" button is greyed out.  With "print to file", the button is
live and the pdf file is successfully created

I can print via lpr.

If, in firefox, I goto localhost:631 (the cups home page on this machine),
I can print test pages to either machine.

Is there a way I can ask firefox to tell me why the print button is
greyed out?

thanks,
allan
