lpt(4)
The current driver is the port of the original lpt driver to the
system. One purpose of this port was to allow parallel port
sharing with other parallel devices. Secondly, inb()/outb()
calls have been replaced by ppbus function calls. lpt is now
arch-independent thanks to the ppbus interface. See for more
info about the ppbus system. The parallel port bus is allocated
by lpt when the printer device is opened and released only when
the transfer is completed: either when the device is closed or
when the entire buffer is sent in interrupt driven mode. The
driver can be configured to be either interrupt-driven, or to
poll the printer. Ports that are configured to be interrupt-dri‐
ven can be switched to polled mode by using the command. Depend‐
ing on your hardware, extended capabilities may be configured
with the command. With an ECP/ISA port, you can take advantage
of FIFO and DMA. In order to retrieve printer info from
/dev/lpt0, just apply the command to the device. If the printer
supports IEEE1284 nibble mode and has data to send to the host,
you will get it. first parallel port driver This driver replaces
the functionality of the lpa driver, which is now defunct. There
are lots of them, especially in cheap parallel port implementa‐
tions. It is only possible to open a lpt port when a printer is
connected and on-line, making it impossible to run when there is
no printer connected. This driver could still stand a rewrite.
