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 : I [27/Apr/2011:16:11:20 +0200] [Job 827] Adding start banner page "none".

Nicolas, That was very helpful. The problem was caused by me, I failed to copy over the ppd files of the printer to the new system. The error log files did not report errors related to not finding the /etc/cups/ppd/printer.ppd file for the printer, but did remind me of the file's need to be present. When I checked it was not present, but was an easy fix. Thank you very much!!!! Greg
