NAME

lp − line printer

DESCRIPTION

Lp provides the interface to any of the standard Digital Equipment Corporation line printers, on an LP-11 parallel interface.  Bytes written are printed. 

The driver has several internal parameters for adapting to the characteristics of various printers.  These parameters are settable, via ioctl(2) call, using the lpset(1) command. 

The FFCLOSE parameter causes one page eject on close.  The default is no page eject on close, because the line printer spooler does a page eject after each file is printed.  No page eject is done on open. 

The CAP parameter determines whether or not the device is treated as having a 96- or 64-character set.  In half-ASCII mode, lower case letters are turned into upper case and certain characters are escaped according to the following table:

{ -
(

} -
)

` -
´

| −
!

~ −
^

The driver correctly interprets carriage returns, backspaces, tabs, and form-feeds.  A new-line that extends over the end of a page is turned into a form-feed.  The default line length is 132 characters, indent is 0 characters and lines per page is 66.  These parameters are also settable by lpset(1).  Lines longer than the line length minus the indent are truncated.
