Printer Configures fine but won't print -- "Client-error-bad-request"

[Benjamin Sher]

Dear friends:

Just installed Fedora Core 6. I am very pleased with its design, wealth of 
applications and professional look and operation. The only problem I've had 
has been my printer. I have no problem configuring my Okipage 10e printer (in 
KDE) as such. It is recognized by Fedora, which selects the correct device 
driver (the same one that works perfectly on other distros) but at the end of 
the configuration it won't print. Instead, I get an error message that says:

"Client-error-bad-request".

I logged out of my user account and logged in to my root account and tried it 
there but I got the same error message.

I'd appreciate your help. Just can't figure out what the problem is.

Thank you.

Benjamin
