lpoptions(1)                                                        Apple Inc.                                                        lpoptions(1)

NAME
lpoptions - display or set printer options and defaults SYNOPSIS
lpoptions [ -E ] [ -U username ] [ -h server[:port] ] -d destination[/instance] [ -o option[=value] ] ... [ -o option[=value] ] lpoptions [ -E ] [ -U username ] [ -h server[:port] ] [ -p destination[/instance] ] -l lpoptions [ -E ] [ -U username ] [ -h server[:port] ] [ -o option[=value] ] ... [ -o option[=value] ] [ -p destination[/instance] ] -r option lpoptions [ -E ] [ -U username ] [ -h server[:port] ] -x destination[/instance] DESCRIPTION
lpoptions displays or sets printer options and defaults. lpoptions shows the default printer options when run with no arguments. Other options include: -E Enables encryption when communicating with the CUPS server. -U username Uses an alternate username. -d destination[/instance] Sets the user default printer to destination. If instance is supplied then that particular instance is used. This option overrides the system default printer for the current user. -h server[:port] Uses an alternate server. -l Lists the printer specific options and their current settings. -o option[=value] Specifies a new option for the named destination. -p destination[/instance] Sets the destination and instance, if specified, for any options that follow. If the named instance does not exist then it is created. -r option Removes the specified option for the named destination. -x destination[/instance] Removes the options for the named destination and instance, if specified. If the named instance does not exist then this does nothing. If no options are specified using the -o option, then the current options for the named printer are reported on the standard output. Options set with the lpoptions command are used by the lp(1) and lpr(1) commands when submitting jobs. ROOT ACCOUNT OPTIONS
When run by the root user, lpoptions gets and sets default options and instances for all users in the /etc/cups/lpoptions file. COMPATIBILITY
The lpoptions command is unique to CUPS. FILES
~/.cups/lpoptions - user defaults and instances created by non-root users. /etc/cups/lpoptions - system-wide defaults and instances created by the root user. SEE ALSO
