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.
