Dan, can you attach the following for each driver/print queue with which you are able to print, but not duplex, always for a job where you select duplex printing in the print dialog:
1. The PPD file of the printer: /etc/cups/ppd/<print queue name>.ppd 2. Original file which you tried to print 3. error_log as described in "CUPS error_log" on https://wiki.ubuntu.com/DebuggingPrintingProblems 4. Captured print job as described in "Capturing print job data" on https://wiki.ubuntu.com/DebuggingPrintingProblems 5. Clone the print queue via the commands
cupsctl FileDevice=yes lpadmin -p <print queue name>-file -E -v file:/tmp/printout -P /etc/cups/ppd/<print queue name>.ppd
Print the same job to this queue and attach /tmp/printout (Use "sudo chmod 777 /tmp/printout" to make the file readable for normal users).
