Manual Duplex Printing in General

[Anonymous]

Hi All,

I'm manually trying to do duplex printing over a network to a server running CUPS connected to a HP2550L Colour Laserjet.

I can enable the duplexing options, and I can get options to do duplex in Windows, but when I try to print with duplexing truned on it just tells me there's been an error.

I've tried manually printing a ps file with duplexing turned on, but nothing at all comes out of the printer so it's failing at the server end.

I've heard that CUPS doesn't do manual duplexing - is this true?

Thanks a lot,

David
