The Parallel Driver, "ibmprint.device"

The "ibmprint.device" driver is fairly simple, and is really intended 
for printers.  It only supports data output, not data input (the PC 
parallel port is not capable of functioning bidirectionally with all
8 bits).  Units 0 through 2 correspond to the IBM printer units LPT1
through LPT3.  To use the driver, put the file "ibmprint.device" into
your "devs: directory", and use the IOWedge program to redirect the 
printer outputs of your favorite word processor or other program.  
No "mountlist" entry is necessary.

An important thing to realize is that most I/O cards do not implement 
the printer LPT1.  LPT1 originally came with the IBM monochrome 
graphics adapter, so clone manufacturers have generally made their 
printer ports correspond to LPT2 or LPT3 (our units 1 or 2), with 
interrupts implemented on IRQ5 or IRQ7.  Make sure of the settings
on your I/O card.
