LPTCONTROL(8)

NAME
lptcontrol - a utility for manipulating the lpt printer driver

SYNOPSIS
lptcontrol -i | -p | -e | -s [-d device]

DESCRIPTION
The lptcontrol utility is used to set either the interrupt-driven, extended or polling mode of individual lpt(4) devices. When a printer is switched from a mode to another, this change will only take effect the next time the device is opened.

Extended mode is anything the parallel port interface can support. For an ECP/ISA parallel port, it may be FIFO+DMA or ECP.

The following command line options are supported:

-i  Turn on interrupt-driven mode.

-p  Turn on polled mode.

-e  Turn on extended mode.

-s  Turn on standard mode, i.e. turn off extended mode.

-d device
    Set the mode of the printer device specified by device. The default value for device is /dev/lpt0.

One of -i, -p or -e must be specified.
