.SH NAME
 | 
						|
lp \- line printer
 | 
						|
.SH DESCRIPTION
 | 
						|
The
 | 
						|
.B lp
 | 
						|
device refers to the line printer attached to the parallel port.  Any byte
 | 
						|
written to this device is printed.  Only one process may have the device
 | 
						|
open.
 | 
						|
.PP
 | 
						|
The
 | 
						|
.B write (2)
 | 
						|
call may return with a smaller count then the number of bytes requested to
 | 
						|
write.  The next write call is then likely to fail with the error code
 | 
						|
.B EAGAIN
 | 
						|
if the printer is out of paper, or
 | 
						|
.B EIO
 | 
						|
if the printer is turned off.
