printer devices
lptcontrol8
A utility for manipulating the lpt printer driver
Usage
lptcontrol {-e | -i | -p | -s
[-d
control_device]}
Overview
The lptcontrol utility is used to set either the interrupt-driven, extended, standard, 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:
-
-e -
Turn on extended mode.
-
-i -
Turn on interrupt-driven mode.
-
-p -
Turn on polled mode.
-
-s -
Turn on standard mode, i.e., turn off extended mode.
-
-d control_device -
Set the mode of the printer control device specified by control_device. The default value for control_device is /dev/lpt0.ctl.
One of -e, -i, -p or -s must be specified.
