I'm going nuts trying to enable double sided for an lab with an KM Bizhub 958 connected to papercut.
I'm using the following lpadmin:
lpadmin -E -p "STPRINT-CommonsFollowMe" -v "smb://stprint.cscc.local/CommonsFollowMe" -P /Library/Printers/PPDs/Contents/Resources/KONICAMINOLTA958.gz -L "Center for Technology and Learning" -o printer-is-shared=false -o auth-info-required=negotiate -o Finisher=FS536 -o PaperSources=LU303
however, the -o KMDuplex= does not work, tried, Single, Double, or Booklet as specified by the lopotions -p name -l
Also using the most current driver, 11.1.1 from 5/16/2018
Anyone have any ideas?
Not sure if this info will help but worth a shot to read over and double check your workflow deploying the printers using lpadmin or lpoptions
