# 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`’.
