I doubt it's an i386 vs x86_64 issue. Printing pdf documunts from the 
command line through cups works fine here on an x86_64 C5 system.

Have you looked at the logs in /var/log/cups/ ?
You could increase the log level to debug in /etc/cups/cupsd.conf if 
nothing is obvious in your current logs.

For reference, with the default "info" loglevel, when printing a pdf 
file I get this in /var/log/cups/error_log :
