lpc

Line printer control program (UNIX)

Syntax:

lpc [command [argument...]]

Options:

See description.

Description:

The lpc utility is a tool to control the print services. There are two sides to the printing process: the enqueuing of jobs and the dequeuing of jobs. Jobs are enqueued by lp and dequeued by the print server (lpsrvr). The lpc utility communicates with the print server to control such things as allowing new jobs to be enqueued, stopping the dequeueing of jobs, reordering jobs in the queue, etc.

The print spooler used is that defined by the LPSRVR environment variable. If LPSRVR is not set, /qnx/spooler is used.

Control commands are specified as additional arguments on the lpc command line. When no commands are specified, they will instead be read from standard input.

Brief online help is available through the help subcommand:

    lpc help [command...]

The help command gives a short description of each command specified. If no command is specified, a list of the available commands is displayed.
