Change cupsctl printer Print Style to 1-sided via script

I want to know this too.

You can run

lpoptions -p printername -l

to get a list of options that the printer supports. Then you just need to figure out which one you want to change and set it with

lpadmin -p printername -o option=value

for example

lpadmin -p treedestroyer -o Duplex=none

by far the easiset way to set print options is to set them up locally, then just copy the " com.apple.print.custompresets" from /Library/Preferences to users

K.I.S.S :-)
