System V Print Subsystem enable Command

Purpose (System V Print Subsystem enable Command)

Enable LP printers

Syntax (System V Print Subsystem enable Command)

enable printers

Description (System V Print Subsystem enable Command)

The enable command activates the named printers, enabling them to print requests submitted by the lp command. If the printer is remote, the command will only enable the transfer of requests to the remote system; the enable command must be run again, on the remote system, to activate the printer. (Run lpstat -p to get the status of printers.)

When changes are made to the attributes of a print device, they are recognized by enable. Therefore to change the definition or allocation for a device, you must disable the printer on that device, change the device, and then run enable. The new device attributes will become effective when enable is executed.

Printer names are system-defined words and as such should be restricted to uppercase and lowercase ASCII characters.

If you enter enable -?, the system displays the command usage message and returns 0.
