lp -- parallel line printer
lp0 at uba0 csr 0177514 vector lpintr
NOTE: This driver has not been ported from 4.4BSD yet.
The lp device supports DEC and DEC compatible printers on the LP-11 par-
The unit number of the printer is specified by the minor device after
removing the low 3 bits, which act as per-device parameters. Currently
only the lowest of the low three bits is interpreted: if it is set, the
device is assumed to have a 64-character set or half-ASCII mode, rather
than a full 96-character set.
If the 64-character set is assumed, any lower case characters are mapped
to upper case; left curly and right curly braces are mapped to left and
right parentheses over laid with a hyphen; grave accents are mapped to
acute accents with overlaid with a hyphen; the pipe bar character is
mapped to an exclamation sign overlaid with a hyphen; and the tilde char-
acter is mapped to a carat overlaid with a hyphen.
The default page width is 132 columns; longer lines are truncated. This
may be overridden by specifying, for example, `flags 256'.
A lp driver appeared in Version 6 AT&T UNIX.
