Using the laser5_duplex or laser5_single definitions from the command line or within xpdf/gv produces a failed socket message when 'lpstat -p -d' is run. Nothing comes out the printer. However, if I specify the default laser5 printer name, the job prints from both the command line and from within xpdf.
I still need to fix this quickly since business checks must be printed single-sided and I need that definition to work for them.
This seems inexplicable to me: the generic definition works, but the _single and _duplex definitions don't.
Your help is still needed.
