Can anyone offer some advice about interfacing a printer to a 3130?
I have a malibu dual mode 200 which I would like to attach to the 3130.
It responds to the print spooler, but it prints rubbish. However, the self-test
mode of the printer prints correctly.
I have made a link between /dev/ttyd3 (the printer is on port 4) and
/dev/lp and have then used lpadmin to introduce the printer to LP.
However, it makes little difference whether I use the 'dumb' filter
in /usr/spool/lp/model, or edit it to make a filter of my own; I just
get different amounts of rubbish coming out of the printer. I assume my
filter is simply inappropriate for the printer.
The printer is set to run at 600 baud (selectable from 110 to 9600),
no parity, start/stop o/p control, ASYNCH data format, 1 start bit,
8 data bits, 1 stop bit. Cable Pins connected are 1-1, 2-3, 3-2, 4-5, 5-4, 6-6,
7-7, 8-20, 20-8.
I know I have to place a suitable stty line somewhere in the dumb
filter to customise it to my printer, but all reasonable (to me!) stty
lines I put in seem to give me rubbish. Also, it is not clear to me just where
the stty line must go in the filter (so I have put it at the start).
Can some knowledgable person offer a few words of help, please?
Am I missing a step somewhere? Any comments welcome!
Many thanks.

I have used several printers on our 3130 with out too much problem.
(That is after I got everything working.) I have conneted a HP ThinkJet,
a Seiko CH-5201 color hardcopy unit, a Tandy 24-pin dot matrix printer,
and a Tektronix 4693D printer to our 3130 through the serial ports
/dev/ttyf2 and /dev/ttyf3. I had to use a serial to parallel converter
for the last three and some extra hardware to get the Seiko to work.
Follow the directions in section 7.9, pages 7-21 through 7-24 in the
IRIS Series 3000 Owner's Guide V3.0 or Appendix C, pages C-21 through
C-23 in the V2.0 Owner's Guide. However, before doing so put the
appropriate filter into /usr/spool/lp/model. Right now I use a Tektronix
4693D connected to the parallel port and two remote printers.
It has been long time since I used the serial ports for printers, I think
the interfaces still work. I think one of the key things in getting the
interfaces to work was to use the timing functions of stty instead of null
character padding.
I am enclosing the interfaces I used on these devices, I used the same
interface for the Thinkjet and Tandy printers:
