NAME

lp − line printer

DESCRIPTION

Lp provides the interface to any of the standard DEC line printers.  When it is opened or closed, a suitable number of page ejects is generated.  Bytes written are printed. 

An internal parameter within the driver 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 sequence of newlines which extends over the end of a page is turned into a form feed.  All lines are indented 8 characters.  Lines longer than 80 characters are truncated.  These numbers are parameters in the driver; another parameter allows indenting all printout if it is unpleasantly near the left margin.

BUGS

Half-ASCII mode, the indent and the maximum line length should be settable by a call analogous to stty(2).
