NAME
lp —
parallel line printer
SYNOPSIS
lp0 at uba0 csr 0177514 vector lpintr
DESCRIPTION
NOTE: This driver has not been ported from
4.4BSD yet.
The
lp device supports DEC and DEC compatible printers on the
LP-11 parallel interface.
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 character 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
’.
