[comp.sys.att] Centronics interface on 3b2

slimick@unix.cis.pitt.edu (John C Slimick) (09/18/90)

I recently replaced an AT&T 479 printer with
a Panasonic printer on our 3b2/400. The problem:
Centronics line 14 is always low coming from the 3b2.
Panasonic assumes that if centronics line 14
(auto-line feed) is low, it should add a LF
after every CR. Result: double spaced print outs.

Is there a simple solution to this? Could it be
shared?

thx

I once had similar problems with a NEC-860 "laser" and an NCR Tower-32.
The solution was to either cut line 14, or cross connect it somewhere
else, though I don't remember the exact details.

Seems like a lot of work.  Why not just edit the interface program
(It's somewhere in /usr/spool/lp.) and add a line like 'stty -ocrnl'?
If you need to know specifics, send me mail and I'll look it up in my
manual when I'm back at work.
