NAME
470 - filters nroff(l) output to AT&T 470 (and C. Itoh 8510) printers.
SYNOPSIS
nroff -T470 files I col -xfp I 470 l lp -dprinter_R
nroff -T475 files I col -xfp I 470 lip -dprinter_R
nroff -T8510 files I col -xfp I 470 I lp -dprinter _R
DESCRIPTION
Input to 470 can be either nroff(l) or col(l) output. 470'soutput should
be sent to raw lp. Col cannot handle eight-bit special characters. 470
expects the same syntax as col for indicating special characters; it sets
the eighth bit on any characters between the ASCII SO (\017) and SI
(\016) characters, and discards SO and SI from its output To pass SO or
SI to the printer (to control double-width printing), precede each with the
escape character.
470 converts LF to CR-LF and it also translates the tty-37 vertical
motion codes (ESC-7, ESC-8, ESC-9) to the correct AT&T 470 vertical
motion codes. 470 issues the correct commands for all reverse or forward
line motion whether 118" or 116" line spacing is set The default
value is 116" line spacing. ESC-B sets 118" line spacing, and ESC-A sets
116" line spacing.
470 sets the printer to incremental mode before the backspace character
and vertical motion codes, and re-sets logic-seeking mode afterward
(unless the printer is already in incremental mode).
The following translations are performed on input characters:
LF output 'CRLF'
so
SI
ESC-SO
ESC-SI
ESC-7
ESC-8
ESC-9
set 8th bit on following characters
stop setting 8th bit
print double width
cancel double width print
reverse 1f
reverse 112 lf
forward 112 1f

col(l), man(l), mm(l), nroff( l), and nterm(5).
NOTES
It is strongly advised to use col with the AT&T 470 & 475 and C. Itoh
printers in order to prevent misalignment of characters caused by reverse
carriage motion.
The AT&T 470 & 475 printers must be set to receive 8-bit characters in
order for special characters to be printed correctly. Set DIP switch 6 on
switch block 2 to "off' or "open" to enable 8-bit characters.
