To be sure, I just did a test:

$ defaults write org.cups.PrintingPrefs User 'ItIsMe‘
$ cupsctl —debug-logging
$ lp -d some_printer some_file.ps
$ grep 'Job xxxx‘ /var/log/cups/error_log > /tmp/temp.log
	where xxxx is the job ID the lp command returned
$ defaults delete org.cups.PrintingPrefs User
	to revert to the previous state

Looking into the saved log file /tmp/temp.log it revealed that the defaults setting
had no effect; the requesting user name was still ma login name.
